Bug 20805: Update child to adult patron process broken on several patron-related pages

This patch fixes a problem with several patron-related pages, where the
"Update child to adult patron" menu item doesn't work. With some pages,
the right category information wasn't being passed from the script to
the template. With some, the right JavaScript variable weren't being
passed from the template to the included JavaScript file.

To test, apply the patch locate some patrons with "child" type patron
categories. With each patron, go to one of the following pages and test
the "update child" process in the toolbar's "More" menu.

 - Circulation ->
   - Batch check out
   - Notices
   - Statistics
   - Files
   - Housebound
   - Delete (test from the deletion confirmation screen).

All test should be performed on a system with multiple adult patron
categories configured AND on a system with only a single adult patron
category.
