Make logistration generally available if feature flag is enabled

Sort Studio video uploads by creation date

Update Footer Copyright Notice as per Legal OPEN-444

Makes logistration available at /login and /register as well as /accounts/login/ and /accounts/register/. In addition:

- Adds support for redirect URLs in third party auth for combined login/registration page
- Adds support for external auth on the combined login/registration page
- Removes old login and registration acceptance tests
- Adds deprecation warnings to old login and register views
- Moves third party auth util to student_account
- Adds exception for microsites (theming)

This provides a better UX for video uploaders, because recent uploads
are readily visible at the beginning of the table.
