+ An abstract codec system, simplifying support for new formats
+ Changes versus BlackAura's patch:
o Consolidated the OpenAL parts into one file
o Changed the function naming scheme to more closely resemble Q3
o Changed the interface to fall back on the "base" sound system
if loading OpenAL fails
+ This is enabled on Linux and MinGW for now, but should work on the
other *nixs with appropriate additions to the Makefile
+ NOT enabled on OS X or MSVC Windows builds
+ Probably breaks the Windows build again
* Retabulated sdl_snd.c and made the messages less verbose since
there do not seem to be many having problems with SDL sound now
* Updated TODO
* Moved ChangeLog to root
* Updated ChangeLog
* s/Foobar/Quake III Arena Source Code/
* Biggest patch EVAR. I wonder how many mail boxes this will fill...
* Moved printing of desired audiospec to before SDL_OpenAudio
* When the computed value for samples is not a power of 2, now pick the smallest power of 2 greater rather than the largest power of 2 smaller
