Bump changes and version

CHANGES.rst

+Changes in synapse v0.11.1 (2015-11-20)
+=======================================
+
+* Add extra options to search API (PR #394)
+* Fix bug where we did not correctly cap federation retry timers. This meant it
+  hours for servers to start talking to ressurected servers, even when they
+  were receiving traffic from them (PR #393)
+* Don't advertise login token flow unless CAS is enabled. This caused issues
+  where some clients would always use the fallback API if they did not
+  recognize all login flows (PR #391)
+* Change /v2 sync API to rename ``private_user_data`` to ``account_data``
+  (PR #386)
+* Change /v2 sync API to remove the ``event_map`` and rename keys in ``rooms``
+  object (PR #389)
+
