[BUGFIX] FAL: Invalid title and broken layout

This fix resolves the issue of the wrong title for FAL irre relations.
Now the title of the sys_file metadata will be displayed,
if there's no title for the sys_file_reference.
Additionally the title, labels and placeholder
will be cropped if necessary.
