@zamiang: Paging support

For starters the posting tool will use pagination to navigate the list views. This does things The HAL Way™ by crawling the `next` link `page` amount of times until it gets the results it wants.

Joining `next`s and making several HTTP requests better than:

`request.get(ARTICLES_URL).query(page: page)`

or

`new Articles().fetch(data: page: page)`...?

Verdict is still out ¯\\_(ツ)_/¯
