Bug 16026 - Use Font Awesome icons on cataloging home page

The cataloging home page has one instance of a Glyphicon. This patch
replaces it with a Font Awesome icon.

To test you must have the EnableAdvancedCatalogingEditor preference
enabled.

- Apply the patch and go to the Cataloging home page.
- Confirm that the "Advanced editor" button uses the "pencil" icon and
  that it still works correctly.
