Controller Support, Visual and UI Changes — Darkest Depths Steam update #349648

Removed cel style shading as the default. You can turn this back on with style number 2 "Cel" in the start HUB. Added controller support. Right now this is just controls in game. I'll work on adding menu support and then things like aim assist/haptic feedback(rumble) in the near future. Updated the UI to be more clean and easier to read. I'll try to make it more stylish later but for now I just want to see my energy at a glance. Changed a pillar model. Adjusted base lighting. Adjusted light sources to be more resource friendly. The flashlight now has some sway. Updated most level art. Increased starting health by 5. Further adjusted enemy spawning for hallways to be more consistent. Fixed an issue with a missing texture. Enemies can no longer shoot through walls. I thought I'd fixed that but I didn't.
