Implemented server side pagination. This is critical for search engines crawlability. A pagination bar is generated during template expansion. SOme benefits include:

- Requires no JS to make functional.
- Standard <a> HTML elements enable search engines to crawl
- Simple and rock-solid
- Very similar to google's search results so familiar to users

This requires corrseponding changes on nodeBB core.
- Disabling client side JS for pagination
- Adding some code to topic and category controllers to generate the data needed for pagination rendering.
