chore(bower): use bower for dependencies

Update angular-app client-side stuff to use bower for dependencies.

Right now this is still working from the AngularJS 1.2.x builds as it is not yet clear that all the dependencies support AngularJS 1.3.

There was only a small amount of refactoring required:

* In angularUI bootstrap, `$dialog` has changed to `$modal` with slight API modifications
* mongolabResource changed both module name (to `mongolabResoureHttp`) and service name (to `$mongolabResourceHttp`)

Closes #238
