* add ability to set path of card image before CARDInit * begin work on updating card class to support gci folders a lot of work will just be directly reading from whatever folder is supplied, instead of relying on an always open FileIO handle * swap to interface system for easier code seperation, begin actually planning out logic for gci loading * fix wrong name for func, add modified time to new gci file entry * get gci folder working tp seems to be happy with everything ive done, the only funcs im worried about are getSerial and getChecksum as those dont do anything atm. * fix createFile not assigning file index to output FileHandle, CARDSetLoadType now takes an enum * make probeCardFile a virtual func so GciFolder and RawFile can both implement their own, bit of cleanup
