Release 1.1

Hi everyone!

This project was a little inactive the last year, it was pretty busy. Thanks to community contributions we have some updates anyway, so we should prepare another release.

I fixed an OAuth-Bug which forced me to login again and again. Also I removed the legacy auth, since its not available in Funkwhale 1.2 anyway. In our other Funkwhale project we use towncrier to keep track of the changes made which needs to be mentioned in the Changelog. I implemented this here, too, and created changelog snippets for all changes since 1.0 (Please review and give feedback).

For your interest, we have the plan to build a python library wrapping the Funkwhale API. Since Mopidy-Funkwhale has the most complete implementation, I will use this as a base. Before I jump into this, I am interest releasing the latest changes, before we break everything again.
