Feature: Upload Button - wrapped with Bootstrap Button. New option 'fileButtonText' to specify a button text.

Feature #3752 / Pills auf mode|modeSql=hidden|readonly setzen - implemented during 'form load' (not dynamic update)

* Broken Redirect after Save - fixed
* Broken same HTML ID for FE copies in a template group. - fixed

Bug #4548 /Template Group: 'form-update' broken - max tg element value/index shown after save instead of last user supplied value, but save is ok.
Neu wird nach dem Speichern das Formular nochmal komplett geladen. Das ist wichtig um die durch aftersave geaenderten Records in die Formularelemente zu bekommen.

ug #4512 | SIP URL does not respect anker token '#'- fixed PLUS: L and type _GET Params included in links which contain a SIP (regular links still open).

Bug #4508 / Form: during Save with FE with 'report'-Note/Values an exception is thrown - report does not expect it would be called without typo3 - but this is the case during save and generating the JSON.

Bug #4504 / Upload Button: required asterik missing after save - seems to be a problem for every element - should be fixed now.

#4495 (New): Upload: Problem if mode is 'required' - part 1: do not set HTML required if a file is already uploaded.

Removed then disabled class from label
