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.

Support.php: new funtion handleEscapeSpaceComment().
Evaluate.php: parse all F|FE.parameter via handleEscapeSpaceComment().
