SOUND OVERHAUL

This update includes a major overhaul to sound, as well as dynamic music.

3D Sound:

This update introduces a new feature called 3D sound, audio now pans, gets quieter/gets louder based on distance and direction. The sound is anchored to world space, so you can easily pinpoint the direction the sound was emitted from. 

Reverb: 

Sounds not emitted by the player now have reverb applied based on distance.

Echo:

Sounds now echo; the further the sound, the longer the echo.

Sound Occlusion:

Sounds behind walls become quieter, the more walls between the player and the sound, the more silent.

Enemy Sounds:

The biggest addition to this update is enemy sounds. The gurgled alien sounds of the Corruptors, the demonic uttering of the Heathen, and the tactical swearing of the Grunt (stolen from Half Life 1, I'll give it back).

Other additions:

Bullet hole decals on walls, attack animations for all enemies, the world rendering is now baked, should always run at 60fps as framerate is capped at 60hz (you could probably run this on a pregnancy tester)
