Release 0.2.38

Please Note: If you are using OS X builds you will need to run a manual migration as part of this release. After upgrading you will need to run this in a REPL: (circle.backend.model.esxi-vm/run-migrations!). Please talk with your account manager if you need further instructions.
The Admin Users page now has links to the builds of each user.
The API has a new endpoint /api/v1/admin/licensing that returns information about the number of seats available, number being used, when the license will expire, and how many inactive users there are in the system.
Fixed a bug where links to the documentation broke.
Various small bug fixes and UI improvements.
