Let us remap menu/ui controls#56

I play with an alternative controller (8bitdo 64). RoA II’s native input layer lets me access the “right stick” as the N64 C Buttons, but my controller has no X or Y buttons, so I can’t ban stages or access control options via the character select menu.

I know you can remap controls within Steam Input, but this adds a extra step on top of everything else, which could be frustrating in a tournament setting.

Would it be possible to let you remap UI actions to different buttons as well as the character actions? Remapping Ban, Player Options, and the Button Test actions to different buttons on my controller would be really great.
