Add preliminary support for PS3 PSP HD Remasters.

It's a hack, but it doesn't/shouldn't affect any games due to how I structured the code. It's based off of BlackDaemon's work(#1494) and has double texture coordinate support now(#2314), so K-ON Live! and other HD remasters will be rendered fine now.  Huge props to @unknownbrackets and @daniel-dressler for their help with coding style, and putting up with my lack of C++ skill(yeah, I admit it.. :) ).
