[Enhancement]: Page by index

[JerryNixon]

Proposal

Consider enabling paging by index only.

Why?

Most UI use simple paging, which is index paging.

Though this would not take advantage of our current cursor approach, it would be the simplest to implement.

Sample syntax

http://server/api/entity?$page=2

Configuration

This would not require any additional configuration change.
