@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.

@dzucconi—This is true. We could just force our UI design to fit our API dogma and remove to ability to bookmark or go to a specific page...

...however to jump back on my soap box:

Restricting our UI design b/c it doesn't work so nicely with HAL seems like we're preferring hypothetical engineering wins over user experience. Dropping pagination for just next/prev is small and maybe worth the UI design constraint—but philosophically I'd rather build the best UI than build around what works best for HAL.
