Added mouse support for linux. It is still rather crude, but it works.

Unfortunately the mouse pointer doesn't match up very well with the IR pointer yet.
Also, I had to add the PointerMotionMask to XSelectInput which adds overhead to the already stressed X event loops.  Five event loops by my count, really?
