Patch: Added a cheats related log, changed color of several positive logs and cleanup.

If any cheats file is not found, the "Not found Cheats file" message will appear with its full path of the cheats file on the log screen.

Changed color of several positive logs to green from grey.

Changed some patch-related variable names. (1) Regular patches (or Game DB); (2) Cheats; (3) Wide screen patches (pnach); (4) Wide screen patches (zip); were difficult to distinguish them from their variable names. FYI: In some places of source code, "Patches" means (1), and "Cheats" means (2, 3 and 4).
