views: factor out paginator component.

Browse Source 
* Refactor the paginator into a ViewComponent.
* Fix inconsistent spacing between paginator items.
* Fix a bug where the sequential paginator generated the wrong next /
  previous page links in the <link rel="{next|prev}"> tags in the <head>.
* Always include the final page as a hidden html element, so that it can
  be unhidden with custom CSS.
* Make it easier to change the pagination window.
