No longer need this since users only will render templates they identify with the ng-template directive. Templates are no longer pre-rendered and cached. This provides for rendering templates via meteor spacebars first and then rendering that output using angular's compile/link functionality.
Pre-rendering with render() and then caching the result was not very flexible in any case if the template was not 'static'. If you needed to generate the template contents, for example, using meteor's rendering engine, and then feed that result into the angular compile/link processor, then using the pre-rendered HTML from the templateCache would not have been helpful.
