Show book details in modal dialog

With them shown in a modal, you don't lose your place in the pagination. If the request comes via Ajax, the minimal layout is used. If via a normal request, the full layout is used. That lets you open the details in a new tab and have the full experience, but if you're clicking through the results of a search, you can view many without losing your place.
