Multiple cheat files and WIP: widescreen cheats

1. Multiple cheats files (at the "cheats' folder) can be loaded, as long as they begin with the CRC and end in '.pnach' (e.g ABCD1234.Persona4(EU).god-mode.pnach)

2. Multiple cheats are also loaded from the Widescreen hacks folder ('cheats_ws'). File names rules are the same as for normal cheats.

TODO: Add config and GUI for widescreen hacks. Right now the cheat files from cheat_ws folder are loaded if cheats are enabled. We need a separate config for that.
