Main: Complete rewrite of the sequencer related audio code to support 3D Audio objects later and especially adressing the animation system problems (see mailing list if interested). Note: Animation is not working yet, so with this commit volume animation doesn't work anymore, that's the next step. Minor things: * Changed AUD_Reference behaviour a little to be more usage safe. * Fixed bug in AUD_I3DHandle: Missing virtual destructor * Fixed enmus in AUD_Space.h * Fixed a warning in rna_scene.c * Removed an unneeded call in rna_sound.c
