Small bug fixes, optimization, and Mac + Linux build

Since I'm nearly finished with my next project, I might as well add a small update to this as well. 

Bug fixes

• Fixed issue where the player gets stuck when colliding with trees.
• Fixed issue where the player can get stuck under the abandoned house or behind a door.
• Fixed issue with doors not closing properly and pushing player.

Optimizations

• Added in baked occlusion culling. Trees outside of camera view were being rendered which was a main cause of lag. Now only what is visible is rendered.
• Reduced render distance. Distance originally cut off way beyond what was possibly visible.
• Tweaked quality settings. Switching from low to lowest had no difference originally. This should also fix a bug where the floor of the abandoned house would disappear.

Builds available for Mac and Linux 

Definitively did not add in a new jumpscare.
