* factored out some of the method dispatching code by adding a dispatchMethod() method to the controller;
* turned the Dispatcher class into simply a function on the base Service class and removed Dispatcher.pm;
* made it possible for services to be both services and objects and provide different services depending on which context they were called in (and used this to make the AdminCommands module actually do what it was intended to in the first place, namely, only work for CommandLine access);
* fixed it so if a service is first created by getServiceList the constructed version will actually be cached;
* made output more generic by allowing services to implement arbitrary parts of the output API, used that to make AdminCommands usable without requiring additional code to support it;
* added some documentation;
* added some dump(10) statements to help debugging;
* fixed the string datasource SQL;
* fixed the DBI database so it can handle errors;
* added tableExists API to the DBI database helper.
Thanks to myk, justdave and zach for some ideas.
