Hayden Hargreaves 71e32f1fd7 (FIX): Created a decent dependency inject architecture.
The system allows services and repositories to be created in the main
server definition and then store them in the context. They can then be
retrieved and mapped onto the injection type and accessed in the
handlers. The handlers can then use the deps to call services. Each
service is initialized with the required repositories so they can be
accessed directly.
