1.3.0.5 - New Acorn Logo

Hey everybody! Here's a pretty minor update:

• New Acorn logo. I made the old one a long time ago. It was crooked. It was bad. This one is good.
  
• Updated Unity version from 2017.3 to 2017.4.whatever.LTS. It really doesn't matter, I doubt it improved performance, and I don't think it changed system requirements. Just thought I'd say.
  
• Got rid of Unity analytics. Apparently I turned them on at some point. I never knew I did. I turned them off not only because I don't use them and don't want you guys to have to worry about data collection, but maybe having them on would require me to say some legal crap I've never said.
  
• Removed some unused assets.
