Show publication year and media format in book details

This is the frontend part of showing more information about the book discussed in [NOTA-67](https://notalib.atlassian.net/browse/NOTA-67).

We'll need to land Notalib/E17#678 as well because we don't export the publication year from the database at the moment.

A live test branch of this pull (based on `master`) can be found here: http://test.m.e17.dk/bookinfo/

@andmand, is this satisfactory?
