quakeio.h -> vfile.h
More diff reduction between trunk and my VFS code. Also took the time to
put some headers in order and fix a few #include's pointed out by moving

thinking :)
set fs_pluginpath to point to the right dir, and set snd_plugin to pick a sound
plugin.
Current issues:
- alsa 0.5 won't build properly, dunno why
- segfault on exit. I think I know the cause of this, and how to fix it
- alsa 0.9, gus, sgi, sun, and win32 havn't been tested
