Bug 15309 - Use Bootstrap modal for cataloging search MARC and Card preview

In order to reduce the number of dependencies for common interactions we
should attempt to use Bootstrap modals in place of Greybox ones. This
patch modifies the cataloging search results page so that "MARC" and
"Card" previews are displayed in Bootstrap modals.

To test:

1. Apply the patch and navigate to Cataloging.
2. Perform a search which will return results from the catalog.
3. Test the "MARC" and "Card" links for multiple results and confirm
   that the correct data is shown each time.
4. Perform a search which will return results from the reservoir.
5. Test the corresonding "MARC" and "Card" links for those results.
