Quake2 skydistance patch

[Nick Warne]

Hi all,

Yonks ago when I was a poor windows user, I added this hack as I used to play 
Quake2 DDay, which has very big maps:

Anyway, since then I moved to Linux and use the great icculus build with 
SDL_GL.  I started playing a map (The Longest Three Feet, quake3 converted to 
Quake2) map - this is a big map, so I missed the skydistance CVAR a lot.

I have just added to icculus build quake2-r0.16.1 - attached are the patch 
files to add the skydistance CVAR and code if you wish to add.   It works 
well in SDL.

Nick
