The goal is to split up the situation between the dashboard
controller and the current dashboard service. I want to be
able to use the routing in order to select various dashboard
controllers, so I can extend the current scripting
mechanism by implementing new dashboard controllers.

However, to do this in a non-insane way, I need to move as
much functionality as possible into services, so the individual
controllers just need to throw the right set of services
together and add a bit of loading logic.
