Added support for controller vibration

With this patch controller vibration is enabled on certain events. You can toggle vibration with "V" on your keyboard.

Vibration should work in singleplayer, in the tutorial and also for both players in the local multiplayer.

Also included are some minor bug fixes and some hard to find easter eggs were added. Don't search for them. They really aren't worth the effort.

Hope you are still enjoying OneJump. Now even more with controller vibration. Have fun!
