Allow input mapping to D-pad and the L/R sticks

[desibwoy]

People should have a choice of whether they want to play with the D-pad, Left stick, or the right stick in tate (vertical) mode. Lemuroid allows editing the input bindings to the Face buttons and L/R buttons, but not to D-pad and sticks. Please allow input binding to these controls so that even beginner players can have a choice of how they want to play the game
