Beta Controller Support + Settings

Howdy, I finally managed to finish adding controller support to the game, aswell as the option to control the ship with your keyboard (WASD and arrow keys). I've currently listed it as "Beta" controller support, but will update the games Steam page to "Full controller support" once I can be sure it is bug free. In addition to that, I've added a couple new settings:

• A toggle to unlock the mouse from the game window

• A toggle to turn off screenshake

• A slider to change the size of the in-run cursor so that it can be see more easily if necessary

Cheers, and thanks for playing
