@smn @miltontony ready for review.

This is almost exactly the same as unicore-cms but I changed Paginator.total_count to do results.count() instead of len(results) for an S object. I also added a paginate filter.

Hm in the original implementation the .count() stuff was implemented in the EGPaginator subclass.

Nothing to change here but just noting that this .count() change already existed.

Oops, I forgot to mention that. I removed EGPaginator and made Paginator handle S objects instead. EGPaginator was doing other stuff like returning a generator that calls to_object. It was meant as a drop-in replacement in unicore-cms, but seemed overkill for springboard.
