- Drops the Team page for privacy and accuracy. I don't want to pressure folks into feeling committed to the project through a page like this, and it also doesn't allow folks any privacy option (as you can hide org membership on your GitHub profile).
- Moves the History page into an Overview page, which includes an updated history page and a quick team blurb at the top.
- Added redirects to the new Overview page from Team and History
