Bug 19785: Move template JavaScript to the footer: Authorities, part 1

Bug 19785: Move template JavaScript to the footer: Authorities, part 1

This patch modifies even more staff client authorities templates so
that JavaScript is included in the footer instead of the header.

To test, apply the patch and test the JavaScript-driven features of the
modified templates: All button controls, DataTables functionality, tabs,
etc.
