[quake2] Quake 0.16 rc2...

[Steffen Hein]

I just checked out current CVS and tested on my machine again (linux-x86). The 
mouse is still spinning around when using SDL software mode and the alsa code 
still doesn't compile (it did with rc1).

When using the softx renderer, quake2 crashes while loading a level:
