Bug 7663 - batch add barcodes to a list

This patch changes the barcode input on add list to a textarea and
process multiples barcodes to allow for adding many items to a list
at once

To test:
 1 - Create a list
 2 - Add some items
 3 - Verify items are added and success reported
 4 - Add these items again
 5 - Verify you are notified they were not added
 6 - Type invalid barcodes into the text area and submit
 7 - Verify you are notifed of failure to add
 8 - Try going to a list that doesn't exist and adding barcodes
  i.e. http://localhost:8081/cgi-bin/koha/virtualshelves/shelves.pl?op=add_biblio&shelfnumber=9999&barcodes=4
 9 - Verify correct error
10 - Try the above but with a list that exists while signed in as a patron
     without lists permission:
     i.e. http://localhost:8080/cgi-bin/koha/opac-shelves.pl?op=view&shelfnumber=3
11 - Verify correct error: "You do not have permission to view this list."
