Neu jeder abgelaufene Lock geloescht. Damit ist ein 'Extend' nicht mehr wirklich machbar.

AbstractBuildForm.php: placeholder

Lock Release now sent asynchronous. Does not work on Chrome when synchron. Still needs changes on Server side to work.

Added some padding to the alert window, removed the rounded edges, removed borders except the one at the bottom.

Changing buttons for the dirty Events depending on status, no an ignore option should be displayed for the user.

Check if Record is already exclusive locked. If yes, show Form in readonly mode.
