Bug fix to OPAC shelf browsing query statement
If the items.location field was NULL, then the current
SQL query would produce no results. I have turned this
into a conditional block that removes the location condition
in the query if the location is not specified.
In addition, there was a small change to opac-detail.tmpl
that changed Library to Shelves when the shelf browser was
open. This removes a potential redundant Library Library
display if Library is contained in the starting_homebranch.
