DSi Menu replacement for DS/DSi/3DS/2DS

@DeadSkullzJr: Updated AP-fix for Pokémon: Refined Gold Overhaul to v2.0.
Box art / Game cover display now supports transparency!
    Useful for if you want to use game logos in the 3DS theme instead of game covers.
Removed broken AP-fix for Golden Sun: Dark Dawn, as nds-bootstrap now properly handles the patching.
Added ESRB ratings for
    Asphalt Urban GT
    Asphalt Urban GT 2
    Black Sigil: Blade of the Exiled
