 Bug 16024 - Use Font Awesome icons on item types administration page

When editing an item type, a Glyphicon is used for the "translate" link.
It should use a Font Awesome icon instead. This patch corrects it.

To test, apply the patch and go to Administration -> Item types.

- Edit an existing item type.
- Confirm that the icon associated with the "Translate into other
  languages" link is correct.
