Bug 16025 [Revised] Use Font Awesome icons on item types localization page

The item types localization page uses a Glyphicon. This patch converts
it to a Font Awesome icon.

Also changed in this patch: "Delete" text has been added to the delete
link, and a dummy "href" attribute has been added to the link so that it
triggers the right kind of cursor. The deletion confirmation JavaScript
has been edited to ignore the default click action.

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

- Edit any existing item type and click the "Translate into other
  languages" link.
- If there is not an existing translation, add one. Close the modal
  window and click the "Translate into other languages" link again to
  redisplay it.
- Confirm that there is a "Delete" link next to your translation which
  is styled correctly.
- Confirm that the behavior of the "Delete" link is correct both when
  confirming and when canceling.

Revision adds the "actions" class to the table cell with the delete link
to prevent a line break between the icon and the text.
