When 546ec1a5 was merged into develop, I accidentally overwrote the change
introduced in debbea5b (pr #1657). Reintroduce it.

Add new room membership APIs

This returns the currently joined members in the room with their display
names and avatar urls. This is more efficient than /members for large
rooms where you don't need the full events.

Read-receipt fixes

Don't ignore read-receipts which arrive in the same EDU as a read-receipt for
an old event.

This should fix the absence of notifications when new receipts arrive.

Add README instructions for OpenBSD installation

Make sure that a user cannot pretend to be a guest by adding 'guest = True'
caveats.

Fix unittests under tox

We now need to set PYTHONPATH when running the unit tests; update tox config to
do so.

Enable guest access for private rooms by default

Log the args that we have on UI auth completion

Logging: Fix console filter breaking when level is DEBUG

Fix preview test

The old test expected an incorrect wrapping due to the preview function
not using unicode properly, so it got the wrong length.

Updates to the README

preview_url_resource: Ellipsis must be in unicode string

Minor updates post-review

The demo client isn't really fit for purpose, so stop encouraging people to use
it.

Add some syntax highlighting

- remove redundant "where's the spec" section: this would belong in "About
matrix", but it's already there.

- E2E is in beta rather than dev

Fix a couple of broken links

Move some bits of the README around. No words were changed in the making of
this commit.

this is rst so name it accordingly
