Ton Roosendaal 069a3c193c Bugfix #27058
Top bar: Add -> Mesh -> UV Sphere + Enter crashed.
It didn't crash with leftmouse, but that was coincidentally working.

Menus were freeing modal handlers in Window, while handlers were still 
in use. Fix provides to tag handlers for being freed now.

Will add on my attention list for more elaborate checking work here, for
upcoming 2.57a I rather stick to minimal change in code here.
