BGE Profile : visual feedback bars and improvements

You can see a screenshot of the funcionality here:
http://wiki.blender.org/index.php/Doc:2.6/manual/Game_Engine/Performance/Display/Framerate_and_Profile

This patch creates a bar-like graph to quickly allow the game dev to see the performance changes.
Also it changes the font to monospace (too allow ' ' padding) and reduced shadow border to
match the blenderplayer one.

Patch finalized and commited at Global Game Jam Vancouver (last one, time to sleep forever now)
