Work on getting notifiers in shape.

- Most important: local (to own region or area) redraw notifiers 
  have been depricated. This is not a good or correct notifier anyway. 
  Notifiers should be signals to other areas.

- Instead use these 2 functions:
    ED_area_tag_redraw(area);
    ED_region_tag_redraw(region);
  It seems to me good convention to keep the area/region redraw tag
  itself protected everywhere, for future improvements.

- Also added a basic WM function that checks overlapping regions,
  and flushes redraws to underlying regions. This makes menus and
  buttons allow to only send local region redraws.
  (Brought back two "swapbuffer indicators" to test this. 

- Todo: area 'action zone' redraws, and fixing other notifiers...
  sending data pointers in a notifier seems to be bad idea.
