Fixes from Earlier Map Generators
- Now when you explicitly save your map files, they are immediately available on your hard drive for testing. Previously, you needed to exit the Map Generator program before they were fully written to the disk.
- Some threading issues were resolved, allowing multiple maps types to be updated after an action is taken instead of generating each map on demand.
- Fixes flower seeding, which was broken for certain types.
- Fixes the biome UNDO, which wasn't completely removing a biome action.
- Fixes the fixed biome growth directions; they were growing in the old directions from years ago, i.e. a North value was applied to East growth, etc.
