Bug 7399: Holds Queue should show reserve notes

Bug 7399: Holds Queue should show reserve notes

The notes for a specific hold, if they existed, were being added to the tmp_holdsqueue
table by build_holds_queue.pl, but they were not displayed anywhere, which seems a waste.

This patch adds the Notes column to the far right of view_holdsqueue.pl.

To Test:

Place a hold with a note
Run build_holds_queue.pl to place it in the Holds Queue
View the Holds Queue; you should see the note on the far right of the table
