Vertex Paint back!

Added WM level "paint cursor" system, which manages a custom painting
cursor for tools or modes. 

- Activate it with WM_paint_cursor_activate(). That function wants two
  callbacks, a poll(C) to check whether there's a cursor in given context
  and ARegion, and a draw(C, x, y) which gets called when appropriate.
- While paintcursor is active, the WM handles necessary redrawing events
  for all regions, also to nicely clear the cursor on region exit.
- WM_paint_cursor_activate returns a handle, which you have to use to
  end the paint cursor. This handle also means you can register as many
  custom cursors as you want.

At the moment, vertex paint mode registers only a mousemove handler,
all other events are still normally handled. This is stuff for the 
future todo.
