Create a Breadcrumb library which has two static methods for_item (which takes a an item and builds the entire breadcrumb for the item) or build (which takes a variable number of Breadcrumb elements and creates a breadcrumb based on the specified elements). Used tag->url() to build the tag album url. Escaped the query string for the search. Tightened up the breadcrumb code in page.html.php. When adding the show query parameter, we can't blindly concatenate using the ? separator. We have to check that we use a & if a query parameter already exists.
