- FIX RE0 GFX fifo errors :D

Browse Source 
- This game read the CPRead pointer when the GP is processing data and after detach the fifo  and attach again an use this pointer for continue, so implement fifo.SafeCPReadPointer pointer.
- fifo.SafeCPReadPointer is updated when (FAKE_GetFifoEndPtr() - g_pVideoData) == 0) to have a pointer without GFX Commands Cut in the beginning of 32 block.
- Reset video buffer when the CPReadWriteDistance is written by the software.
- This commit is experimental please test a lot your games.
