gsdx-hw: Add an OI hack for Sonic Unleashed. 

It will allow to render the shadows properly.

Rendering pattern is:
Save RG channel with a kind of a TS (replaced by a copy in this hack),
compute shadow in RG,
save result in alpha with a TS,
Restore RG channel that we previously copied to render shadows.
