US Flatlands Revamped

The US Flatlands map has been completely revamped in this beta version!

Changelog v5.1.0:
- Fixed pallet spawning issues
- Re-added distillery and brewery productions
- Added a new brewery
- Removed flax and hemp fiber due to issues
- Adjusted seasonal growth to prevent withering when not using seasonal farming (experimental)

No new savegame should be required.

This version includes Jinkou's crop and production pack. A big thanks to all contributing modders!
