S_Init() is now where it belongs--outside of VID_Init(). I think I did
manage to update every target. If I missed one, kill the sound.h include
and remove S_Init() from VID_Init().
New Cvar: r_sky, defaults to 0, turn it on if you want to use skyboxes.
Cvar r_skyname can actually be used now I _think_, need another skybox
to test it. Quake2000's instructions were used in the skybox stuff but,
as all know by now, our tree is so different from anyone else's that I had
to redo a number of things. But thanks all the same--cut the time spent
debugging it in half. I also want to thank whoever did the night skybox
on the MegaTF page I used to test. Looks great on start map!
New GL-specific Cvar: r_conspin, defaults to 0. Turn it on. You can turn
it off too. Shamelessly ripped from QER.
