to be divisible with 4 anymore, you can use what you want
-moved sound buffers back in mem2, idk but for wiiflow it gives
a better result
-added mem2 memalign placeholder for new memory manager (after
a week still everything but finished)
-updated other small things, cleaned up source structure a bit
* Fixed gc_discHdr struct
* Updated aiff decoder to dimok's code (Thnx)
Todo for GC disc dumper:
