Eager Beavers

Neoforge release!

• Improved AI slightly, beavers should more reliably place dam blocks
• Beavers fight for blocks less
• Unfortunately the tail animations on the Beaver Hat are broken in Neoforge, I'll fix this in a later update but for now the beaver hat is just static
• A config file! Now you can adjust the spawn rates if they're too low/high
• a creative tab in the menu (its sparse but the items are no longer just in miscellaneous)
