Added code (some possibly temporary?) to load voices.wad. Fixed several problems with playing of voice sounds - especially had to add a dynamic hashtable of voice sfxinfo_t's because Choco won't tolerate overwriting them once they've been used (see channel_playing array in i_sdlsound.c) - PROBLEM: Random Z_Malloc failures when trying to play sounds. Cannot catch in debugger so far. Subversion-branch: /branches/strife-branch Subversion-revision: 2065
