Subject: Patches for photon port of SDL

Hi,

A couple more patches for photon and the nto audio. Adds mouse grabbing
support, fixed cursor images, unicode keyboard events (though no unicode
data on kye release, is that a problem?), hopefully fixing some audio
lag problems, and a few other fixes.

Thanks,
Julian Kinraid
