Beaver Statistics

Adds a tab which shows the top 3 behaviors your beavers and bots are spending their time on. Hovering over the behavior shows the breakdown of the actions done during that behavior. For example `ProduceWorkplace: 95%` behavior means 95% of that character's time is spent producing an ouput. Hovering over the stat shows `95. 2% Produce` and `0. 3% WalkInside` meaning 95. 2% of the time they're working, and 0. 3% of the time they're walking to work. There are mod settings available, which can be adjusted in case performance is impacted. Please comment if there are any issues, I'll do my best to help!
