Patch 5.1.3 Optimizations

Greetings Everyone,

Small patch today. I recoded some of the heavy hitting scripts so the game should be much more optimized now. Additionally added a normal map to Ice nodes. Hopefully should fix any dancing colonists may do around nodes as the collision has been removed.

Spectroscopy also does not work in this build. I will fix that tonight when I release the Mac version.

Cheers, Cameron
