According to the following table: * MOUSE_L -> DIG * MOUSE_R -> PLACE * SCROLL_UP -> HOTBAR_NEXT * SCROLL_DOWN -> HOTBAR_PREV This commit entirely removes the special KeyTypes used for joysticks. Support for the MOUSE KeyTypes had already been removed in the main game code without adapting the joystick code, breaking joystick input. This commit restores joystick functionality.
