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

AbstractBuildForm.php: fixed broken JSON Object array

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

AbstractBuildForm.php: fixed 'checkbox' update (api/load.php) - raw values like 'yes', 'no', 'enabled', 'disabled' are not understandable by the client (delivered via JSON) and needs to be converted to true/false.
