pyvera 0.2.21 fixes the fact that use of requests.get was not using a
timeout. Some times (after a few days of use) the pyvera poll loop
would hang indefinitely on a requests.get of the event interface. This
would cause the pyvera thread to hang completely. It would also
prevent graceful shutdown, as pyvera does a thread join.
The new version uses a timeout, so that we won't lock up any more.
