AdminstratorManual/Index.rst: Update config.qfq.ini description to new parameter 'class'. Remove 'DB_NAME_TEST' cause that is only interesting to PHP Unit Tests and not to enduser.

Store.php, QuickFormQuery.php: Refactor building STORE_SYSTEM. Make it more generic if new parameters are introduced. Setting up new config.qfq.ini built in defaults and form defaults at one place. Renaming of parameter names in config.qfq.ini to STORE_SYSTEM at one place implemented with an extensible array.
AbstractBuildForm.php, BuildFormBootstrap.php, BuildFormTable.php: User constant F_CLASS  in $this->formSpec['class']
config.qfq.example.ini: comment empty variables - the new default setting is, that empty parameter in config.qfq.ini means EMPTY, not UNDEFINED.

Add FORM_BS_LABEL_COLUMNS, FORM_BS_INPUT_COLUMNS, FORM_BS_NOTE_COLUMNS to config.qfq.ini.

AdministratorManual/Index.rst: added notes to install php-intl, new config.qfq.ini parameter (see above).

Create function `Database->getNativeFormElements()` to unify all needed actions on fresh loaded FormElements like explodeParameterInArrayElements, duplicateRetypEelements, copyAttributesToFormElements. Native FormElements will be loaded on 4 different places in 3 classes.

HelperFormElement.php: Moved copyAttributesToFormElements() from QuickFormQuery to HelperFormElement.
AbstractBuildForm.php, BuildFormBootstrap.php, QuickFormQuery.php : Use of Database->getNativeFormElements()
Database.php: HelperFormElement::copyAttributesToFormElements()

FormAction.phhp, Store.php, AbstractBuildForm.php, Constants.php, QuickForemQuery.php, Index.rst: Added STORE_BEFORE, #3146

AbstractBuildForm.php, QuickFormQuery.php: Added specific validator.js error text definition to remaining HTML form elements. Not sure if all of them will benefit of it.

Added validator.js attributes 'data-pattern-error', 'data-rquired-error', 'data-match-error', 'data-error' to be specified in config.qfq.ini, Form or FormElement. Detailed setting will overwrite generic setting. If none is specified, take validator.js defaults.

AbstractBuildForm.php, BuildFormBootstrap.php, BuildFormTable.php, Constants.php, QuickFormQuery.php, Index.rst: Implemented Paramater 'extraDeleteForm' for 'forms' and 'subrecords'. Doku update.

QuickFormQuery.php: for modeForm='Form Delete' the 'required param' are not respected - this makes sense, cause these parameters typically filled in newly created records.

QuickFormQuery.php, FormAction.php: '#2931 / afterSave Hauptrecord xId nicht direkt verfügbar' - load master record again, after 'action'-elements has been processed.

FormEditor: 1) design update - new default background color: grey. 2) per form configureable background colors, 3) Optional right align of all form element labels.
BuildFormBootstrap.php: added new class name 'qfq-label' to form labels - needed to assign 'qfq-form-right' class. Changed wrapping of formelements from 'col-md-8' (wrong) to 'col-md-12'.
QuickFormQuery.php: Set default for new F_CLASS_PILL & F_CLASS_BODY.
formEditor.sql: New default background color for formElements is blue.
qfq-bs.css.less: add classes qfq-form-pill, qfq-form-body, form-group (center), qfq-color-*, qfq-form-right

delete.php, Delete.php: reformat
Link.php: typo

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().

Sendmail.php: Update class to send mailand to log them in table mailLog.
AbstractBuildForm.php: refacxtured columnname 'value' to be used via constatn FE_VALUE.
formEditor.sql: renamed FE.typ 'sendmail' to camel hook 'sendMail'. Changed FormeElement.mode from 'select' to 'radio'. Added empty table 'mailLog'.

1) '{{id:R0}}' now gives the correct record id, even on records which are 'new' (id is 0 at time of save) - '{{id:R0}}' can be used 'fileDestination' to build pathFilename.
2) Fixed problem with non existing uploads: in the past a sip has been saved instead of an empty string in the current record.
3) Fixed problem with a) choosing an upload file, b) deleting them immediately and c) pressing 'save'. Non existing temporary uploaded file has been tried to move to final destination.

Documentation/UsersManual: FormElement 'File' update
AbstractBuildForm.php: Extend upload structure with EXISTING_PATH_FILE_NAME.
QuickFormQuery.php: 'late save' of uploads implemented.
Save.php: upload columns are not saved during the first save - instead they are saved later.

QuickFormQuery.php: missing 'r' in forms forces no longer an exception, instead r=0 is the default. This is usefull in report for 'new' links to forms (it's not necessary to specify r=0 in '_pagen') as well as on record definition `form=person`: `r=0` is not needed anymore.

delete.php: extended to support returning JSON, HTML redirect (Location) or HTML error messages.
Report.php: new adjustDeleteParameter()

Report.php, Store.php, QuickFormQuery.php: configuration option 'SESSION_NAME' removed and hard coded to 'qfq'.
Session.php, Sip.php: function checkFeUserUid() moved from Sip to Session. Will be called by using 'Session'. SIP's now stored one level deeper in $_SESSION['qfq'][...]. This makes it easier to destroy the SIP cachae in case of login/logout. Destroying the whole $_SESSION var is not a good idea.

Constants.php,QuickFormQuery.php: Introduced new variables, Bodytext: no var 'form=' or empty var 'form' are now allowed. If given, no form will be load -nothing happens.

Report.php: set default value for $t3data["uid"]. $bodyText now given to process() instead of the constructor - makes testing easier.
QuickFormQuery.php: applied change of 'bodytext' from Report.php.

Implemented form.requiredParameter - comma sepated list of SIP parameter. If at least one of them is missing in the SIP store, the form won't be loaded.

HelperFormElement.php, Logger.php, FillStoreForm.php, AbstractBuildForm.php: fomatting form element name.
Support.php: add setIfNotSet()

After creating a new record and still open form: a new sip is created and transfered to client. Attention: 'new + save + modify + save again' still create two records (error).
AbstractBuildForm.php: buildNewSip() renamed to buildHiddenSip(). Call of buildHiddenSip() moved from tail() to process(). buildHiddenSip() returns JSON code too.
BuildFormBootstrap.php, BuildFromPlain.php, BuildFormTable.php : removed call buildNewSip()
