Bug 13943: Prevent the deletion of items if the user cancels

On the edit items page, there is some weird JS code: if the user clicks
on the delete link and then cancel, the item is deleted anyway.

It's caused by the following JS code in browser.js
  $('a[href*="biblionumber="]').click(function (ev) {
      ev.preventDefault();
      window.location = $(this).attr('href') + '&searchid=' + me.searchid;
  });

Test plan:
- Do a search with multiple results
- Go to the detail page (make sure results browser shows up!)
- Use the "Edit items" link from the toolbar
- Delete an item (try both way)
- Choose "cancel"
- Delete an item (try both way) and confirm the deletion
You should see the browser after the deletion and the item should have
been deleted correctly.
- Edit an item (try both way)
You should see the browser (did not work before this patch)

Note: Before this patch, the 2 first columns didn't contain the
edit/delete item links, now it's only the 1st one.
