Title: Make sorting optional or user controlled

I don't want to add tons off options to the backend. so I'm thinking it would be nice to allow visitors to sort by comment weight or by date. Just need to implement an ajax callback.

Or just add a filter on the comment output, pass a sorting argument to the comment function.
