Scaffold generator in service shell

[pond]

Since the (possibly unwise) introduction of on-by-default framework search for created_by there's been a chance of a 500 being raised for a service which doesn't have the relevant column and doesn't opt out of that search either.

It's also a little tedious to hand-type in the implementation, interface, resource, model and comprised_of declaration updates for a given resource-model pairing by hand.

A Rails-like scaffold generator could help a lot here. Tracking this under Hoodoo and under the service shell.
