Load Event by ID, incorporate data into form.
Workaround ember behavior introduced here: https://github.com/emberjs/ember.js/commit/fc4df510ffcd37cb185d3521c58e22881e09218d
* Need to not use capital first char on model properties.  Even thought the work fine on display just bomb on tear down of route.
Create BaseRoute and BaseObjects to encapsulate shared functionality, moved moveUpData there, but should still create one top level function that both call.

Still need to:
transitionTo event/update from event/create without the ajax call re-loading the Event JSON that we got back from save.
moveUpData as one top level function that the Bases call
