Page number greater than total_pages should be allowed

[nicksanders]

The pull request below breaks a number of clients we have that increment the page until the entries array is empty.

Would you be open to a pull request making this configurable?

Same here. Some endpoints just sent the list of items, other send the total pages, current page, etc. I will convert now all to return total pages, current page, etc.

I'm not interested in allowing pagination beyond the end of the collection. See #71 for a proposed solution.
