Added b intheknow service and feed manager

Ive added a service to get the bintheknow feed from tumblr and a controller to manage the auto loading process.

added unit tests - integration tests to follow
I haven't got a proper answer. But if you think of the MVC pattern in its simplest terms.

Model - Business Logic
Controller - Handles Input
View - Handlers Output

The feed is the input. So the how it is collected is the controllers job.
The manipulation of it is business logic so should be in the services/model/proxy however you are naming that layer.

We don't have a view really. But the ***output*** is the JSON that is the result of the webservice.
