plegall 1c545c601b feature 724: improved "add tags" form. Instead of a big list of checkboxes,
displays a dynamic list of tags with jQuery, with suggestions based on
existing tags and the ability to create new tags on the fly.

The change was applied only on admin/picture_modify.php for test purpose.

Note : FCBKcomplete 2.7 had a bug on "remote tag" click, and the bug was fixed
on 2.7.1. But the suggestions were not working with 2.7.1. So I took the 2.7
and applied the tiny change to make the "remove tag" click work.
