ADDED AUDIO! WAV working perfectly
Added libogg, libvorbis and libvorbisfile to 3ds_portlibs. You will need to compile thems using make build-portlibs. Opening OGG files works but they play badly. Added a very simple error handler in main.lua Added audio example. Renamed isGfxInitialised to isGfxInitialized. Did you know? The audio module is the longest ctrµLua module.
