Subject: [PATCH] Allow admin to change the names of filtered groups

This feature lets one mimic a custom field by allowing admins to change
the text that appears next to each group's check box, via drush.

The json format is a bit more nested, but indented json can be used. An
exmple is included in CRM/Contact/Form/Edit/TagsAndGroups.php.
