A number of improvements, focusing mainly on the Unity -> Max/MSP pipeline.

• multiple sounds now played over Max/MSP connection
• more data being sent to Max/MSP including:
  • absorption of sound, so sound loses volume when colliding
  • surface roughness, as a factor of sound diffusion
  • occlusion, which may have applications for simulating echoes
  • attenuation, which simulates sounds traveling through different substances
• quick player prefab switcher implemented, now one build works for all platforms
• models made with special sound maps
  • absorption is red, roughness is blue, etc
• snow particles and color grading added
  • establishes a cold environment, looks pretty
