Change the order of "if flag" checking so that weightpaint and vertex paint modes catch the UKey for undo before face select.
I was having to switch out of face select to undo then go back into face select mode.
FaseSelect+WeightPaint is very usefull, while wait painting its very unlikely youd want to be UV mapping faces.
Also Made all space.c's c++ comments into C style.
