Cwcheat

Okay here's the progress on CWcheats. Ported from JPCSP mostly. Some functions are still missing. Still needs a way to interface with PPSSPP and initialize. 

Circular dependency needs to be resolved between the two classes. It may be possible to just omit the use of the second class object in CheatsGUI, not sure yet. Compiles fine after commenting it out. Haven't tested actual cheats yet, due to initialization problems.
