Bug 19753: Move template JavaScript to the footer: Acquisitions

Bug 19753: Move template JavaScript to the footer: Acquisitions

This patch modifies some staff client acquisitions templates so that
JavaScript is included in the footer instead of the header.

This patch adds a JavaScript file, acquisitions-menu.js, which controls
the highlighting of the current page in the sidebar. Highlighting will
be temporarily broken for pages which have not been modified to include
this file

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