Terralith

 - The Overworld now generates randomly according to the world seed, rather than having a fixed seed. Thanks to Haven King for allowing me to use Seedy Behavior.

- Removed the random teleport at world creation.

- Added the Fortified Village structure. This is a new, slightly more advanced village that can sometimes spawn in any plains-group biome. Many thanks to Whale for building the houses, and to Hex and koolkid94 for making loot tables for this structure!
- Snowy Mountains now has the correct sky color.
- Added another Shrubland entry as a barrier between Shattered Savanna and snowy biomes.
- There should be a dramatic reduction in the number of stray items underground when the world is generating.
- Fixed some issues with snow in Scarlet Mountains
- It should be essentially impossible to spawn in a cave now
