[feature request] "Beaten" and "Not working" metadata options.

[Loquo]

Good afternoon.

I really would like to mark in any way what games can't be played properly (for example, that ones that should be played with periphericals like lightguns, keyboards type controllers, trackballs, spinners, NES power pad, ect., or... bad emulation), and in the other hand what games I have beaten.

I would be neat that we could mark any game as "not-working" or "beaten", in the same way you can mark any game as "favorite", "hidden" or "kidgame".

I would like this options work this way:

• Not working: The game in the game list has a "warning icon" or a "wrong icon". Other way could be attenuate the color of the font for the games marked as "not working".
• Beaten: I would be nice to mark games beaten with a medal icon or similar.

Thank you very much.
