Further work on new "text search" button.
- Now allows to browse items (mouse, arrow key)
- Assigns active value
- Uses different backdrop to distinguish from popup menus
- Cleaned API for it, so it can be used nicely generic
Also added a search menu, which shows all currently working
operators: CTRL+ALT+F. (mind the looks, it needs some tweaks!)
To make a menu activating a button I've added a new event...
could use some tweaks.
Important note: the callback to pass on "old string" for text
button (bone rename) couldn't work yet, added first code for new
callback, but has to be worked on further. When bone rename gets
added it can be tested.
