Add TestController (#50)

This can be used in tests to get access to a controller that behaves
just like a dev controller but doesn't require the normal Command bits
(UI, etc).

This can be enhanced over time as needed; for now it's pretty simple but
it's good enough to be used for API tests. A simple project create/read
API test is added as well, which serves to show the programmatic model
(as well as test those functions at the API level).
