Use waitlock flag in lock()

[razed11]

lock() does not wait the lock timeout before failing. The waitlock flag (bit 0) is not being set. Is there a reason why this flag would never be set? If there is, perhaps add a default wait = False argument?

    def lock(self):
        "Send lock command"
        if self.link is None:
            self.open()

        # flags = 0

        # TODO: Added waitlock flag.
        flags = 1 

        error = self.client.device_lock(self.link,
                                        flags,
                                        self._lock_timeout_ms)

        if error:
            raise Vxi11Exception(error, 'lock')
