Bug 23885: Move staff client search results JavaScript into separate file

This patch moves most of the JavaScript embedded in results.tt into a
separate file. The JavaScript that remains on the page is everything
which requires processing by Template Toolkit. This is limited to
variable definition.

To test, apply the patch and perform a catalog search in the staff
client. On the results page, test that JavaScript functionality has not
been affected:

 - The search results toolbar should "float" as you scroll
 - Select all and Clear all
 - Default search term highlighting; Unhighlight and highlight controls
 - Adding and removing one or more items from the cart
 - Adding one or more items to a list
 - Placing one or more holds my making selections and clicking "Place
   hold"
 - Browse selected records
 - Z39.50 search (search form should be populated with your search
   terms)
 - "Show more" and "Show less" links in the facets sidebar
 - Book cover image services: Amazon, Coce, local covers, etc.
 - Open a patron record and click "Search to hold"
  - Perform a search and select one or more results
    - Test "Place hold" from the hold menu in the toolbar
    - Test "Place hold for..." from the hold menu in the toolbar
    - Test "Forget..." from the hold menu in the toolbar
 - In Tools -> Patron clubs, locate a club with enrolled members
   - From the "Actions" menu, select "Search to hold"
     - Perform a search and select one or more results
       - Test "Place hold" from the hold menu in the toolbar
       - Test "Place hold for..." from the hold menu in the toolbar
       - Test "Forget..." from the hold menu in the toolbar
