McRegion: Ignore files which don't have a valid file extension

Browse Source 
previously a file with a 4-letter name ending in 'mca' in the region folder of a PMAnvil world would cause the world format to be unrecognized. This happens because strrpos() returns false when the substring isn't found, which gets coerced to 0 when used in addition.
