CheatsModule + CheatsSearch + FrameLimit hotkey + Multithread Shaders

Same as below. Rebased to master on 10/11/2017, with added pull request for the multithreaded vertex shaders.

Also removed cheat search for float/double, since they were kinda broken with build.

for cheats, make sure you have a 'cheats' folder in your citra user dir.
