[#16] reload dashboard list when renaming dashboard

From what I've seen, using events for such things is sort of an anti pattern in AngularJS applications. Basically view should mutate based on data changes. In this case we need to have a Dashboard service that knows about the list and also manages the updates to a single dashboard (which will update the list).

From https://github.com/angular/angular.js/wiki/Best-Practices:

Only use .$broadcast(), .$emit() and .$on() for atomic events
Events that are relevant globally across the entire app (such as a user authenticating or the app closing). If you want events specific to modules, services or widgets you should consider Services, Directive Controllers, or 3rd Party Libs

Personally, at the beginning I used events for something similar and very soon things went sideways.
