- FIFO changes - minor cleanup, code organization based on Nolan's changes
- Minor code cleanup
- CommandProcessor changes - Allow BP IRQ clearing for either raising or falling edges.
- Revived old SetFifoIdle code

Gets Pokemon XD to run, but will crash to any CPU-GPU desync. Other games like Metroid Prime, look happy with the new FIFO changes.

Please report any problems.
