Bug 9771 [Revised] Replace YUI buttons on acquisitions basket groups page with Bootstrap

The acquisitions basket group page has a toolbar with YUI-generated
buttons and menus. It should use Bootstrap instead.

This patch removes the YUI menu buttons altogether, replacing that
functionality with the sidebar menu now included on other acquisitions
pages (See Bug 8913). The "New basket group" button is now styled by
Bootstrap.

Other minor changes: Corrections of invalid markup, improvement to
breadcrumbs.

To test, view the basket group page and confirm that the toolbar button
looks correct and works correctly. Confirm that navigation works and
that functionality of the basket group edit page is not affected.

Revision adds an explicit width to the basket-grouping form columns
so that they don't stretch too wide (and far from each other) when
the browser window is very wide. This better replicates the layout
of the previous version.
