Enable loadingRoute on all application states.

- Upgrade to jQuery 1.10.2
- Convert all `success` and `error` ajax callbacks to `.then` calls.
- Instantiate content within the `load` method on both the cluster and ring pages so the `.model` method can return promises
- Tweak the visual output of the loadingRoute
- Remove generated templates file and generated vendor js file.
- Add error handling to cluster and ring states so we can transition and see the error message instead of getting stuck
- Add error message functionality to ring page
