Update to support RimWorld 1.4.

I got this to compile with Rimworld 1.5 but it still breaks due to runtime issues during map generation

Let me know how you'd like me to share, should I commit or fork

Absolutely incredible. A major part of the issues with updates have always been fixing things that weren't broken prior (like map loading in 1.3 and the addition of DLC, so many things to write patches for). It's still a major feat to get things compiling.

Would be great if you could open a PR via fork so we can merge the changes into dev.
