Bug 29609: Centralized code to build the link to a biblio detail page

There are 2 prefs that control the default view of biblio detail pages:
IntranetBiblioDefaultView for staff and BiblioDefaultView for OPAC.
There are as well viewISBD, viewLabeledMARC and viewMARC to allow/don't
allow access to those page for staff members.

This code need to be in a single place to avoid discrepancy.

Test plan:
Play with BiblioDefaultView and IntranetBiblioDefaultView and confirm
that the links of biblio point to the correct view.
