Tomtoolkit

- Updated TNS broker to support new requirements for user agent headers.
- Added list endpoint for ``Group`` API.
- Updated Gemini facility to improve compatibility with TOM Toolkit.

What to watch out for

- Users of the TNS will need to add ``bot_id`` and ``bot_name`` to their ``settings.BROKERS['TNS']`` ``dict`` in addition to the existing ``api_key``.

* Adds `api/token-auth` endpoint in order to support token authentication for Django Rest Framework.
* Removes Facility Status from Target Detail page to the Observations nav-bar menu, improving Target Detail page load time.
* Recent Photometry table corrected to include only photometry specific to the Target Detail page Target
* Fixes an issue with inaccurate display of photometric filter data from MARS

Note that in order to take advantage of the move of `facility_status.html`, it will be necessary to modify any custom `target_detail.html` or `navbar_content.html` templates, if they have been implemented.

What to watch out for

- ``settings.INSTALLED_APPS`` will need to include ``rest_framework.authtoken``.

This release fixes an error requiring min lunar distance for spectroscopic submissions.

This release adds the following:
