audio mixer revamped to cope with threads. 'cache' memory functions no longer used for audio. added windows acm code to decode mp3 files. audio playback rates scale with game speed. snd_playbackrate added to control the rate of new samples. sv_gamespeed no longer needs a map change. fixed '=' on german keymaps and in_builtinkeymap 0 (and similar issues). bug: keybind names still use US keymap. added support for rmqe's 24bit network precision. fixed byterate reporting to no longer be protocol-dependant (nq rates are no longer wildly inaccurate). removed waterjumping when already dead. fixed model matrix for viewmodels (modelview unchanged), thus fixing rtlighting on viewmodels. Added bspx support for rgblighting, lightingdir, and (preliminary)brushlists. git-svn-id: https://svn.code.sf.net/p/fteqw/code/trunk@4001 fc73d0e0-1445-4013-8a0c-d673dee63da5
