This release updates the `GenericAlert` in the broker interface to return extras and aliases in the `to_target()` method. It also adds a management command, `setdefaultextras.py`, that will ensure all `Targets` have an entry for the specified `TargetExtra` with the value being the default value specified in `settings.py`.

This release updates the `GenericAlert` class to return a dict of `TargetExtra` data and a list of `TargetName` values, and updates the view to save those for any alerts saved as `Target`s.

This release upgrades dependencies for bugfix releases of Django and django-extensions.

This release addresses the following:

- Adds a Supernova Exchange-styled spectroscopic sequence observation form.
- Adds an association between the user that submits an observation request and the resulting ObservationRecord.
- Hides comments for targets that the user does not have permission to view, and hides them for unauthenticated users.
- Sorts instrument and filter lists in the LCO observation form.
- Fixes padding on the observation form.

This release requires a migration.
