Text to go in the release notes:
These patches introduce a new script to replace the `j2a.pl` script with a more flexible set of options.
`misc/cronjobs/update_patrons_category.pl` can now be used to update patrons who are older or younger than their patron categories to a category chosen by the user.
Additionally, this script allows users to specify a fine total to update patrons, to use any specified borrowers field, and to run by category and/or branch.
The intention here is to assist in automating updating patrons for schools or libraries where patrons are regularly changed - patrons with fines can be moved to 'probational statuses' or patrons without fines can be moved to 'privileged statuses'.
The flexibility should allow for various workflows to be automated via cronjob.
