@jcredding I just thought of this, but we don't want to be doing `view.partial` to render partials.  I'd prefer to just call `partial` in a template.

I think we need to make the scope a template is rendered in a first-class citizen and it should provide the `partial` method and any other template helpers we want to provide.  We don't _have_ to make it configurable from the server or handler (where a plugin could add stuff to it) right now though.
