新版改进如下：

- R3000air:
* Improved several branching and exception handling logics, relating to block
splitting and optimizations of blocks/loops.
* Fixed several bugs in the register mapping / allocation system.
* Redid the strict register mapping mode's api (again ... >_<)
* Improved the interpreter's handling of AddressError and Overflow exceptions.
- GSdx: bit more work on the vertex buffer, and broken ffxii fmv fixed again.
- Added VIF wait to MFIFO, fixes Crash of the Titans graphics
- Another µVU typo, fixes silent hill 2 but probably not nothing else.
- Guess im just a jackass, do do do, oh *ahem*... This fixes Jackass :P
