Ability to open .7z and other archive files. If more than one valid rom in the archive a dialog should open with a list of ROMs.

I think we should port over the GENS .7z system as it is the emulator that has this best implemented.

For reference, FCEUX, GENS, Nestopia have this feature.

it would be very nice the 7zip support on this emu, like de Gens-rr should be show a rom dialog when you open a rom compressed in this format, there a lot of ppl that say but why? only if you need a few games for play, but it is tedious always descompress only for a bunch of games.
