Bug 33071: Show tooltip when hovering on home icon in staff interface breadcrumbs

This patch modifies the breadcrumbs WRAPPER in html_helpers.inc so that
the default "Home" link has a title attribute set to "Home."

To test, apply the patch and view any page which has been updated to use
the breadcrumbs WRAPPER. For example, cities administration, the
staff interface home page, the about page.

Hover your mouse over the house icon in the breadcrumb navigation and
you should see a "Home" tooltip.
