Fix issue with per page dropdown
Fix issue: Non-functioning search bar within advanced search page
Changed Homepage Journal search to search against Journals and not periodicals
Request: Addition of link to Inter-Library Loan webpage for relevant items.

This request resulted in the refactoring of the Library items controller.  The LibraryItemsController now handles the Jquery requests for holdings on the search results pages - the LibraryItem model contains logic to
test for availability, inter-library loan etc. (now available in search results). HoldingsRecordController has been removed.
