Miscellaneous Strange Gamepad Behaviors

[zicklag]

• For some reason when using a gamepad the jump height is way lower than normal.
• You can't do the slow-falling thing that you can do on the keyboard.
• When you start the game with a gamepad plugged in, it doesn't successfully detect it, without you unplugging it and plugging it back in.
• It'd also be good to update the keyboard and controller bindings in the README
• The second gamepad's fire and pick up buttons are backward compared to the first gamepad.
