Added wait parameter to disconnect.
If wait=True, then the disconnect call will block until
the send queue has emptied.
WARNING: Using wait=True when more stanzas are being added to the
queue than can be processed such that the queue is never empty
will cause the disconnect call to block indefinitely without actually
disconnecting.
