render_to_response does not work on newer django, so it needs to be replaced. And using a speicfic context actually overcomplicates things, it's easier to just use a wrapper function. For those cases where we don't need NavContext, just use render() (the new shortcut function from django), which also removes the need to use RequestContext.
