Delete posts with three-dot "more options" menu
The main challenge here is making the posts go away on the feed (like on the video below, except it should actually not break the feed afterwards)
This can be accomplished by having the feed be backed by a Room database. That would also let us make the offline functionality be better, and generally be more robust and appear smoother.

Also look at https://gitlab.epfl.ch/debeule/paginwithnetworksamplesimplified or the example that was adapted from: https://github.com/android/architecture-components-samples/blob/master/PagingWithNetworkSample/README.md
We have already spent a lot of time on trying to make this work, but hopefully this time it will get done...
It's done now, so this should be do-able
