[quake3] Mp3 support patch

[Zachary J. Slater]

Thilo,
If you really feel that the code is solid, and won't change much, apply 
it to the trunk, but not the rc branch. I have no qualms about mp3 
decoding support being bad (I was never concerned about patents) at this 
point, neither Tim nor Ludwig have voiced opinions for or against (I'd 
like one or both of them to do so).


About mp3 for this project in general.
I don't feel great about it, I'd rather just stick with ogg vorbis, but 
if it attracts more developers to the project, and projects using it 
like Tremulous and other mods turned stand-alone...
