#3253: STORE_TYPO3: steht waehrend Update / Save nicht zur Verfuegung - wird aber benoetigt. Bsp: feUser, beUser, pageId, ...

Thought that problem of #2064 is based on #3253 - that was wrong.
#3253 implemented, but not heavily tested.

#2064: problem was that for a non existing tablecolumn, has been searched for a default value - which obviously does not exist. In AbstractBuildForm.php, Line 419, a check implemented if the current FormElement is an existing tablecolumn. If not, do not change the empty value.

FormAction.php, FillStoreForm.php, Store.php, QuickFormQuery.php, Save.php: Refactor setVarArray() to setStore()

#3253
FillStoreForm.php: If there is no STORE_TYPO3, get the old values from SIP: CLIENT_TYPO3VARS.
Store.php: new function fillTypo3StoreFromSip(), copyT3VarstToSip()

FillStoreForm.php: fixed problem with checkBoxes in templateGroups. During fillStoreForm the template group has been expanded to all possible elements - the logic for checkboxes expected that at least the '_h_<fe name>' Post Variable exist - which is not true for unexpanded elements.

AbstractBuildForm.php: implemented function templateGroupCollectFilledElements(). Add function.

AdministratorManual/Index.rst: extend sphinx setup doc, fix typo
UserManual/Index.rst: add doc for templateGroup
FillStore.php: Implement save for templateGroup

Default fuer Store Prioritaet hat sich geaendert: alt='FSRD', neu='FSRVD' - damit wird ist es ueberfluessig den V Store anzugeben.
Variable '_filename' umbenannt in 'filename' und verschoben von STORE_FORM nach STORE_VARS. Damit ist es ueberfluessig eine Sanatize Klasse anzugeben.
STORE_VAR hat zwei neue Variablen: 'filename', 'fileDestination'.
Bei Form-Action Elemente gibt es zwei neue Typen: 'sqlBefore' und 'sqlAfter'

Index.rst: Dokumentation auf V2 angepasst. Doku fuer V1 hat es nie gegeben.
FormAction.php: Moved function initActionFormElement to HelperFormElement::initActionFormElement(), Implement sqlBefore & sqlAfter for Action Elemente.
HelperFormElement.php: new class initActionFormElement(), initUploadFormElement().
FillStoreForm.php, AbstractBuildForm.php, Evaluate.php: Implemented the $skip parameter to suppress unwanted variable expansion during form load.
Constants.php: New STORE_USE_DEFAULT, VAR_FILE_DESTINATION, VAR_FILENAME,FE_SQL_AFTER, FE_SQL_BEOFRE, FE_TYPE_UPLOAD.
Evaluate.php: moved 'decryptCurlyBraces()' up, in order to  create better error messages.
Save.php: new doUploadSlave(), implement 'Upload advanced mode'.

CODING.md: update docs for situation 'new record already saved'.
FillStoreForm.php: In case of form load with r=0, the submitted form element names are does not contain the effective record id - workaround implemented.
Session.php: refactored clear(), create unsetItem().
Sip.php: new buildParamStringFromArray(), updateSipToSession().
Store.php: For r=0 SIPs always add a uniqe parameter.
AbstractBuildForm.php: modified message for subrecords on new record.
QuickFormQuery.php: create unique SIP on form load.

UsersManual/Index.rst: updated
FillStoreManual.php, AbstractBuildForm.php: new constant FE_TYPE_EXTRA.

FillStoreForm.php, AbstractBuilForm.php, Support.php: replaced 'dateFormat' with 'FE_DATE_FORMAT' where appropriate.
AbstractBuilForm.php: buildDateJQW in a first version.

FillStoreForm.php, AbstractBuilForm.php: rena,ed buildFormElementId() to buildFormElementName(), deleted: builddateJQW(), copied buildDateTime() to buildDateJQW - but not coded.

FillStoreForm.php: fixed typo.
AbstractBuildForm.php: fixed broken if statement.
TestFormEditor.sql: extend formElement.modeSql.

DynamicUpdate for checkBoxMulti: not possible at the moment - a persistant store per browser tab is necessary. Some work already done.
FillStoreForm.php: clientValues will be copied to STORE_FORM if mode=show|requiered or flag 'dynamicUpdate' is set. Fixed bug with additional ',' in collectMultiValues().

FillStoreForm.php: Recode. Class Evaluate will be instantiated only once. collectMultiValues() recoded not to use arrays anymore, instead a string with the final values, seperated by comma, is returned.

CheckBox Multi: checkboxes are now builded with uniq html names. This is necessary for the client, to assign values correctly to multiple checkboxes during form update by JSON data.
HelperFormElement.php: new prependFormElementIdCheckBoxMulti()
FillStoreForm.php: new collectCheckboxMultiValue(), process() recoded to collect checkBoxMulti values to one element.
AbstractBuildForm.php: checkBoxMulti elements: a) no longer contains an '[]' at the end, b) get individual names

Support.php: If FE_MODE_SQL is given, overwrite the static option.
FillStoreForm.php: Evaluate loaded elements to get FE_MODE_SQL evaluated.

Recode: fromelement.mode='readonly' new implemented on client, by using CSS attribute 'disabled'. The HTML atrribute 'readonly' is fine for pure 'input' elements, but does not work sufficient for 'select', 'checkbox', 'radio'. Also, the label (left of input) and note (right of input) are now grayed out if set to 'disable'.
FillStoreForm.php, Save.php: strings replaced by constants. New central function getfeMode() used by getJsonFeMode() and getAttributeFeMode()

Formelement.mode='lock': removed, cause it seems that there is no difference to 'readonly'. Inside the code, there is no difference
UserManual/Index.rst: doc updated
FillStoreForm.php, Save.php: same functionality like FE_MODE_READONLY - removed.
formEditor.sql: definition updated

Support.php, FillStore.php, AbstractBuildFrom.php, BuildFormPlain.php, BuildFormTables.php, Constants.php, Save.php, BuildFormPlainTest.php

FillStoreForm.php: added HelperFormElement::explodeParameterInArrayElements($feSpecNative);

AdministratorManual/index.rst, UsersManual/index.rst: Configuration & Documentation.
Sanitize.php: code rewrote to use Support::dateTime2mysql().
Support.php: add dateTimeTegexp()
FillStoreForm.php: use of Support::setFeDefaults($formElement). Format date/datetime/time values
Store.php: redefined various functions to be 'static'
AbstractBuildForm.php, Constants.php: added date/datetime/time to tables. Various new functions.
Save.php: FE die nicht uebertragen wurden (typsicherweise weil leer) werden neu mit eimem leer String gesschrieben - sonst ist es nicht moeglich  Eingaben wieder zu loeschen.
formEditor.sql: Felder date/datetime/time neun implementiert.

FillStoreForm.php: SIP Parameter without a corresponding FE have not been saved in the record: fixed

AbstractException.php: If exist, print Form And FormElement names.
HelperFormElement.php, Logger.php, FillStoreForm.php, AbstractBuildForm.php: fomatting form element name.
Support.php: add setIfNotSet()

Sanatize.php, FillStoreForm.php, Constants.php: Preparation to throw more detailed exception for misconfigured min|max values - code not enabled.
Support.php: date format extended to accept yyyy-mm-dd too.

 formEditor.sql: Form and FormElement field 'name' is now 'required'

Refactored sanitize functionality: Form save, form update and client are now handled with the same regexp. Form save and update use the same code to sanatize. SANITIZE names are now equal in FormEditor and in Store. New class SANITIZE_ALL_MIN_MAX_DATE.

OnArray.php: moved inputCheckPatternArray() to Sanatize.
Sanatize.php: complete rewrote of sanitize(). Everything is regexp based now.
FillStore.php: validateValue() removed, use of Sanitize::sanitize instead.
Store.php: adjusted change of Sanitize:sanitize signature.
AbstractBuildForm.php: defined class global variable $inputCheckPattern and initialize them during construct(). Variables, submitted by POST, are now correctly sanatized according their FormElement definition. getInputCheckPattern() adjusted to new/changed SANITIZE definitions.
Constants.php: added SANTIZE_ALLOW_: MIN_MAX, MIN_MAX_DATE, EMAIL, PATTERN, SANITIZE_EXCEPTION, SANITIZE_EMPTY_STRING
Save.php: use of Sanitize::sanitize instead of validateValue()
formEditor.sql: order of FormElement.checkType changed to 'most used first'.

load.php: implemented
FillStoreForm.php: implemented
Store.php: phpunit test complains about 'store already filled'. Option set to explicitly allow rewrite.
AbstractBuildForm.php: Added new mode 'FORM_UPDATE'. Elements additionaly create json code. 'data-load' attribute will be added to form elements, if 'dynamicUpdate=yes'
  elements(): added call by reference parameter $json, to return the generated json code.
BodyTextParse.php: added 'r =' as a new 'start new line' indicator. This was necessary at least for phpunit tests to run.
BuildFormBootstrap.php: buildPill() passes json data structure.
BuildFormPlain, BuildFormTable.php: doSubrecords()  passes json data structure.
Constants.php: New FORM_UPDATE, SQL_FORM_ELEMENT_SIMPLE_ALL_CONTAINER, ERROR_FORM_NOT_FOUND, API_FORM_UPDATE
Evaluate.php: Exception text enhanced.
QuickFormQuery.php: FillStoreForm.php included. Automatic detection of FORM_LOAD and FORM_SAVE removed. Instead the mode are given explicitly. mode=FORM_UPDATE implemented.
Save.php: added TODOs in code.
formEditor.sql: reformat code. Add 'FormElement.dynamicUpdate'. 'FormElemente.checkType': 'number' replaced by 'digit'. Added 'alnumx', 'digit'. Form 'form', 'formElement': output of 'title' replaced by 'name' - outputting 'title' confuses the user (tries to show records which do fit to the formEditor) and might produce recursion in evaluation (did not understand why, but happens). FormEditor: implemented 'dynamicUpdate', escpecially the 'type' select list will be adjusted dynamically.
