Bureaucracy review updates and hello world test
* Fleshed out client-side Agent class, made abstract * Delegate the creation of the bureau director to subclasses of BureauClient * Moved BureauDirector's BureauReceiver and Subscriber implementations to anonymous classes that delegate to protected methods. * Use SafeSubscriber * Added new service method for notiyfing the server when the creation of an agent fails so that the registry is not perpetually waiting * Made BureauCredentials more conformant * Made BureauRegistry respond properly to client logging off * Got rid of superfluous uses of safeToString * Changed Launcher to CommandGenerator and now use ProcessBuilder and copyMergedOutput * Changed bureau process parameters to server name and port instead of URL git-svn-id: svn+ssh://src.earth.threerings.net/narya/trunk@5030 542714f4-19e9-0310-aa3c-eee0fc999fb1
