Notably this adds support for Django 2.1, unblocking upgrading from 2.0.
The custom job details API `NumberInFilter` has been removed, since it
wasn't working after the breaking changes in django-filter, and is not
really needed now that the job details API has pagination enabled, so
has a default `LIMIT 2001` applied to queries.

Since it turns out the `ignored_updates` setting refers to the versions
that should be ignored, rather than the versions that are safe (which is
the opposite of pyup).
* Adds a configuration file for Dependabot:

* Converting pyup ignore entries to dependabot equivalents.
* Removes the badge for pyup
(Dependabot doesn't yet have an equivalent badge.)
