Bug 13121: Move search results "action" links ("Place hold," "Add tag," etc) into include file

This patch moves markup for controls repeated across several OPAC
templates into a single include: Place hold, Request article, Add tag,
Save to lists, and Add to cart.

To test, apply the patch and view the following OPAC pages:

 - Search results
 - Shelf contents view
 - User tags list

On each of these pages all the controls should work correctly:

 - Place hold
 - Request art
 - Add tag
 - Save to lists
 - Add to cart
