User Registration Form

When a new user signs in via CILogon, they will be prompted to enter new registration details in a modal.

- This modal will currently pop up on every page view via the backbone router
- Attempts to pre-populate the name field, works with Google but I have no other credentials to test with
- Multiple phone number support using backbone.forms list editor with a custom editor for phone number object types
