Bug 13055 - Show budget name when editing it

This patch adds the budget name to the page heading when editing a
budget. The patch also similarly corrects the page title during edit
operations and fixes some inconsistency in the breadcrumbs.

To test, edit an existing budget (Adminitration -> Budgets) and confirm
that page title, breadcrumbs, and heading look correct.
