add a new field to IEmulator: bool BinarySaveStatesPreferred { get; }. a core should set it to true to indicate that it would prefer to save and load binary savestates (but both types must be supported). set to true on 7800, gb, dgb, gba, n64, snes, saturn cores, as they all create text savestates that are simply dumps of the binary savestate. for the moment, frontend does nothing with this new information.
