This change allows services and auth handlers to specify their own ARGS lists that requests can then gather and feed into the ArgumentParsers they create. Arg routes are now actual objects (or for declarative use, attrgetters) as opposed to magic values. Requests needing to call other requests can re-use their own service objects to propagate the args that the latter gathered from the command line. Configuration files are parsed much earlier than they used to be and can now cause BaseCommand.__init__() to fail. BaseCommand.run() handles this. Config objects gained the concept of a "current" region and user, which services can set as they parse their command line args. These values are used as defaults when one goes to look up options. BaseCommand.DEFAULT_ROUTE is now an attribute/property, default_route. BaesCommand.print_result is now a noop. Define it yourself if you need a tool to output something during that step. BaseRequest.ACTION is now BaseRequest.NAME. This change breaks a large number of internal APIs. Docstrings are horribly out of date at this point and should be fixed fairly soon in a future commit.
