Committing patch "[#27676] Change window size/resolution in realtime" by me.

Description:
This patch allows the user to change the size of the window (or the resolution in fullscreen mode) using the new bge.render.setWindowSize() method. This only works in the Blenderplayer since it doesn't make a whole lot of sense for the embedded player.
