Every robot/data API operations are prepended by robot.notify operation to make sure that the wave server's info about robot capabilities stays up to date. However, the Java Robot API doesn't allow to update the capabilities hash dynamically during runtime. It's a pity since the server supports it, and there be very good reasons for a robot to update the capabilities based on the robot's state. In my case, that would allow to create a framework to dynamically plugin proxies into host robot and then update the capabilities based on the requirements of a specific proxy.

Please review the patch at: http://codereview.waveprotocol.org/539001 (it's really a small one)
