F6 menu "redo last operation" now works, mostly :)

Try it in editmode on add-UV-Sphere, or Subdivide, those work
fine. Transform ops have some feedback issues or so.

This is a temporary commit; brecht will take this further with
nice code (event system doesn't make menus as active region
but sets the original context instead, as stored in ui handler.)
