better default keybindings

[coldenate]

I think there is a more ergonomic and easy to predict default binding. i'll include this in the big bug fix soon.

West button - forgot/again. max negative difficulty
North Button - card is hard
south button - card is good
east button - hide the answer (would probably be expected to mark as easy, but I think it makes more sense for it to hide the answer if it's shown. kinda like B is back button [B is commonly the east button])

D-pad (North, East, South, West) - Hard, Easy, Good, Forgot

Right Joystick Left and Right - move back and forth between cards

Left Joystick left and right - simple selector. if this is activated, convert button layout to different one designed for a selection mode. South or primary bnutton (A) becomes confirm and B becomes back.

Left bumper - hard card
Right bumper - good card
Left trigger - forgot
right trigger - easy

menu should have > mark as leech, reset card, and it sohuld ideally open the normal menu and use the selector.
