Bug 17147 [Revised] Streamline messages following batch record modification

This patch changes the display of informational messages during and
after the batch record modification process. Instead of showing a
separate dialog for each record modified, messages are now grouped into
one dialog.

To test, apply the patch and clear your browser cache if necessary. You
must have at least one MARC modification template defined.

- Go to Tools -> Batch record modification.
- Submit a list of biblionumbers which contains at least one number
  which doesn't exist in your database.
- Confirm that warning and success messages are grouped instead of
  showing in separate dialogs.
- Submit a list of biblionumbers using a MARC modification template
  which contains no actions. Confirm that the resulting error message is
  correctly formatted.

Revision formats the error messages without the unordered list, which
was giving them padding which didn't look correct inside a dialog.
