Eager Beavers

BIG UPDATE! Sorry this has been a long time coming, but I wanted it to be as good as I could make it for now. Updates

• Beaver overspawning SHOULD be fixed! Please let me know through discord if it's not.
• Beaver lodge structure added
• Many, many bugfixes and tweaks:
  • Beaver dam building should be much more efficient
  • Beavers use a reservation system to make sure two don't go for the same block
  • Beavers will remember where the tree they knocked down was before going for a new one
  • Restrictions on what a Beaver can chew have been tightened, so they shouldn't eat your house anymore
  • Taming was removed cause it wasn't doing much
  • Beaver swimming was improved
  • Beaver AI should also be improved in general
