Quick edit for how often birds were utilizing flight movement.

Balance pass for a few minor issues and changed some birds to now be zone limited instead of penned.

Quick balance pass for things like meat amount, egg nutrition, etc, based on vanilla birds and other birds from my More Birds mod series

Added modded biome support

Some minor tweaks, I realized I had left out a section of the def that makes the birds wander away.
