#3447 / Icons das man im FrontEnd direkt das gewaehlte FormElement im Formulareditor bearbeiten kann
AbstractBuildForm.php, BuildFormBootstrap.php, BuildFormTable.php: Function createFormEditorUrl extended to accept parameter, to make it more generic (best would be to use the 'Link' class). Build the FormElement Edit symbol as together with debug stack symbols

''abel' and 'note' are fixed - 'value' is still not updated, open.
HelperFormElement.php: buildFormElementName() had some issue if there was no $formElement[FE_NAME] defined. New workaround: take the $formElement[FE_ID] instead.
AbstractBuildForm.php: creation of JSON has been missed - now fixed. The $value is rendered (recent value), but probably the client is not prepared to update a non-HTML-input field. This has to debug with RO.

The new implementation creates empty fake instances of all copies of templateGroup FormElements. Those are empty. Before save, the submitted form values will be expanded with the empty fake templateGroup FormElements and such empty values will be saved.
FormAction.php: Rename constant SQL_FORM_ELEMENT_TEMPLATE_GROUP to SQL_FORM_ELEMENT_TEMPLATE_GROUP_FE_ID - to be more precise.
HelperFormElement.php, Database.php: new function explodeTemplateGroupElements()

Fixed missing initialisation of $storeUse.

#3431 / typeAheadSql: columnname 'key' is a reserverd SQL statement - replace by 'id'. Additional the parametername 'typeAheadLdapKeyPrintf' renamed to 'typeAheadLdapIdPrintf'.

AbstractBuildForm.php: Constant renamed.
Database.php: update function makeArrayDict() to reflect name mapping.

AbstractBuildForm.php: for Form subrecord columns, the default width limit of 20 chars are disabled in 'nostrip' is specifed.

AbstractBuildForm.php: Saving 'extra' FE in STORE_SIP has been done with inappropiate FE_NAME. Correct is the pure FE_NAME, without any extension like recordId. Unessary and broken decoding removed.

HelpFormElement.php: Introduced new constants HTML_DELIMITER_NAME, HTML_DELIMITER_ID
AbstractBuildForm.php: Saving 'extra' FE in STORE_SIP has been done with inappropiate FE_NAME. Correct is the pure FE_NAME, without any extension like recordId. Unessary and broken decoding removed.

Manual.rst: commented handling of 'comment character' and 'escaping of leading/trailing spaces'
Support.php: new funtion handleEscapeSpaceComment().
Evaluate.php: parse all F|FE.parameter via handleEscapeSpaceComment().

AbstractException.php: Changing 'getTraceToString()' to 'getTrace()' causes trouble if there is an exception during formLoad. Rendering error messages will be redesigned (#3424)

SaveTest.php: examine php unit problem on CI - reswapped update & insert again. Use global $db instead of local.

SaveTest.php: examine php unit problem on CI - disabled two checks to see if phpunit now runs through.

AbstractException.php: Stacktrace is now submitted as an array and not as '<pre>' text - the '<pre>' is sanatized by the client and has no effect.

Database.php: Added function hasLimit() and makeArrayDict().

Manual.rst: Update Doc for new option 'bsColumns'
Config.php: Copy new element from general config.
Store.php: set default for 'bsColumns'.
QuickFormQuery.php: wrap whole form in 'col-md-XX'

BuildFormBootstrap.phpL #3413 Form ohne Pill hat kein padding am Rand. Fix: falls kein Pill vorhanden ist wird neun zusaetzlich ein col-md-12 geliefert.
