This will allow to save hotkey option toggling to the ini which
should fix gui updating with hotkey toggles.
Note: Render hw/sw switch doesn't work.
Also update some options that didn't have hotkey nametag.
This pull request is for the pending reorganization of the folder structure on GSdx,
making it better organized and easier to work with.
Also remove unused GSTextureFX.cpp file.
