Do not address namespace with `QfqNS` in Object definitions. Instead, use `n`. This might have screwed up the code. We'll fix as we go along.

Support.php: Tooltips will be encoded with htmlentities.
QuickFormQuery.php: Show symbol `debugshowBodyText`

qfq-bs.css.less: Tweaked less. Added new class for spinner. Changed display type of input[type=file].
FileUpload.js: every callback will be called with the originating file input element as first parameter.
QfqForm.js: Add spinner on upload.

Support.php: dateTime2mysql implemented.
Constants.php: add ERROR_DATE_TIME_FORMAT_NOT_RECOGNISED

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.

On submit succes, if we don't navigate away from page, apply possible form updates, as received from the server.

tablesorter.html: does now feature grouping.

QfqForm.js: Form refresh is now known as form update. Form updates receive more elaborate response from server.
