* - Use proper MD5 validation The method TLoZ was trying to validate it's baserom was different from basically every other ROM game. Almost all the other ROM games use the same method as each other (except for the external patchers like FF1 and SoE, and OoT has its own special handling that's vastly different), so updating TloZ to match. Also got rid of the checksum attribute for the TLoZDeltaPatch as it didn't seem to be used anywhere, so felt it was unnecessary and partially confusing to have it right next to the hash attribute that is actually used. * change error message to reference MD5
