Make collection navigation more compact

[Kristina Hoeppner]

The navigation bar for a collection takes up quite a bit of space and the buttons for previous and next pages are far apart making it cumbersome to jump between them when wanting to go back and forth.

This change brings the buttons closer together and also re-styles the navigation bar so it is more differentiated from page headings.
