Surface "Number of entries" in SiteCatalyst & ReportBuilder

[#1]

We often need to determine how many unique items (page names, sections, products, etc) contributed to the "total" metric in a report.

We can sometimes try to page-forward some significant number to find the end -- thanks for that -- but it should be a something shown at the bottom of the page near the total.

Had already posted this here:

Oh sorry, I had forgotten about that one -- and I had even promoted it!

I was really pushing for adding it to ReportBuilder but then remembered it wasn't in the UI either.

I'll restate as one of two improvements to ReportBuilder.
