In get_recent_events_for_room, get the full event json rather than just the event_ids so we don't have to do so many db queries

Don't perform the check in auth.is_host_in_room but instead do it in _do_join
and also assert that there are no m.room.members in the room before doing so.

+Changes in synapse 0.6.1 (2015-01-07)
+=====================================
+
+ * Major optimizations to improve performance of initial sync and event sending
+   in large rooms (by up to 10x)
+ * Media repository now includes a Content-Length header on media downloads.
+ * Improve quality of thumbnails by changing resizing algorithm.
+
+Changes in synapse 0.6.0 (2014-12-16)
+=====================================
+
+ * Add new API for media upload and download that supports thumbnailing.
+ * Replicate media uploads over multiple homeservers so media is always served
+   to clients from their local homeserver.  This obsoletes the
+   --content-addr parameter and confusion over accessing content directly
+   from remote homeservers.
+ * Implement exponential backoff when retrying federation requests when
+   sending to remote homeservers which are offline.
+ * Implement typing notifications.
+ * Fix bugs where we sent events with invalid signatures due to bugs where
+   we incorrectly persisted events.
+ * Improve performance of database queries involving retrieving events.
+
+Changes in synapse 0.5.4a (2014-12-13)
+======================================
+
+ * Fix bug while generating the error message when a file path specified in
+   the config doesn't exist.
+
+Changes in synapse 0.5.4 (2014-12-03)
+=====================================
+
+ * Fix presence bug where some rooms did not display presence updates for
+   remote users.
+ * Do not log SQL timing log lines when started with "-v"
+ * Fix potential memory leak.
+
+Changes in synapse 0.5.3c (2014-12-02)
+======================================
+
+ * Change the default value for the `content_addr` option to use the HTTP
+   listener, as by default the HTTPS listener will be using a self-signed
+   certificate.
+
+Changes in synapse 0.5.3 (2014-11-27)
+=====================================
+
+ * Fix bug that caused joining a remote room to fail if a single event was not
+   signed correctly.
+ * Fix bug which caused servers to continuously try and fetch events from other
+   servers.
+
 Changes in synapse 0.5.2 (2014-11-26)

+Windows Install
+---------------
+Synapse can be installed on Cygwin. It requires the following Cygwin packages:
+
+ - gcc
+ - git
+ - libffi-devel
+ - openssl (and openssl-devel, python-openssl)
+ - python
+ - python-setuptools
+ 
+The content repository requires additional packages and will be unable to process
+uploads without them:
+ - libjpeg8
+ - libjpeg8-devel
+ - zlib
+If you choose to install Synapse without these packages, you will need to reinstall
+``pillow`` for changes to be applied, e.g. ``pip uninstall pillow`` ``pip install
+pillow --user``
+
+Troubleshooting:
+
+- You may need to upgrade ``setuptools`` to get this to work correctly:
+  ``pip install setuptools --upgrade``.
+- You may encounter errors indicating that ``ffi.h`` is missing, even with
+  ``libffi-devel`` installed. If you do, copy the ``.h`` files:
+  ``cp /usr/lib/libffi-3.0.13/include/*.h /usr/include``

+Media Repository 
+================
+
+*Synapse implementation-specific details for the media repository*
+
+The media repository is where attachments and avatar photos are stored.
+It stores attachment content and thumbnails for media uploaded by local users.
+It caches attachment content and thumbnails for media uploaded by remote users.
+
+Storage
+-------
+
+Each item of media is assigned a ``media_id`` when it is uploaded.
+The ``media_id`` is a randomly chosen, URL safe 24 character string.
+Metadata such as the MIME type, upload time and length are stored in the
+sqlite3 database indexed by ``media_id``.
+Content is stored on the filesystem under a ``"local_content"`` directory.
+Thumbnails are stored under a ``"local_thumbnails"`` directory.
+The item with ``media_id`` ``"aabbccccccccdddddddddddd"`` is stored under
+``"local_content/aa/bb/ccccccccdddddddddddd"``. Its thumbnail with width
+``128`` and height ``96`` and type ``"image/jpeg"`` is stored under
+``"local_thumbnails/aa/bb/ccccccccdddddddddddd/128-96-image-jpeg"``
+Remote content is cached under ``"remote_content"`` directory. Each item of
+remote content is assigned a local "``filesystem_id``" to ensure that the
+directory structure ``"remote_content/server_name/aa/bb/ccccccccdddddddddddd"``
+is appropriate. Thumbnails for remote content are stored under
+``"remote_thumbnails/server_name/..."``
