Controller Update

Introducing the controller update. And few other stuff.

• Controller mode option available in game settings. This option only changes the visual tutorials/tips/hints in the game. Means you can play the game both on keyboard+mouse and controller without changing any setting.

• Crosshair sensivity slider available in game settings. This option only changes the speed on controllers.

• David seemed like little clunky character, so now he has a bullet time when he switches to his gun in air. It's really cool.

• Also Jason has it on his leap but it's just to slow him down a little and it's not that huge change compared to David.

• Few level updates: enemy positions, lightning,

Right now I will be working on secret levels and better demo. Thank you.
