GamePad support.
Added 2020-01-05 21:40:30 +0000 UTCI got the gamepad and i'm rebuilding the whole gameplay/ui anyway, so it would be nice to include a gamepad support. I'm calling all the fellas who used to play with gamepad, tell me all your secrets! I mean what's the most important things about gamepads I should know? What's must have and what's no-no, what's default buttons for interaction&navigation, e.t.c.
