* Remove roomserver test again (was merged back in)

* Update documentation

* Docker updates

* More Docker updates

* Update Docker readme again

* Fix lint issues

* Send final event in `processEvent` synchronously (since this might stop Sytest from being so upset)

* Revert "Don't report event rejection errors via `/send`, since apparently this is upsetting tests that don't expect that"

This reverts commit 368675283fc44501f227639811bdb16dd5deef8c.

* Don't report any errors on `/send` to see what fun that creates

* Enforce state key matches sender

* Do the same for leave

* Various tweaks to make tests happier
