New optional gamefix detects when a full motion video runs and temporarily switches GSdx to software rendering mode.

This is a workaround for the many FMV issues that occur in hardware rendering and that will take a while longer to get a proper fix.
It doesn't have any checks for the current video mode, so don't put GSdx in software mode and expect this to adapt, okay? :p
Note: It's possible to get crashes from switching renderers so please report those if you get them.
