Bug 15091: Batch Checkout: Set titles above result tables

Bug 15091: Batch Checkout: Set titles above result tables

This patch is to clarify the results that are displayed while performing
a batch checkout.

It is not the full solution for what is described in the video in
comment #2, but it tells the user what the information in the table
is about.

A second patch is planned to address the case where the issues are confirmed
but not can be fulfilled because the user's fines reach the threshold while
checking out the items.
