Blender 2.5 project: added first more complex handler + operator

- on mouse-over edge, you can drag area borders around.
- note it's a handerized system now, so it updates UI while you
  move mouse.

Feedback needed:

- read bottom part of the screen_edit.c file. It's the proposed
  method for adding tools and handlers. I think it's close, but
  might need some tweaks.
