Bug 10516 - Improve titles, breadcrumbs, and confirmation messages for Z39.50 server adds and updates

The template for adding/editing Z39.50 servers shows the same title,
breadcrumbs, etc. for add and edit operations. This patch creates
separate text for each case.

To test, try both adding and editing a Z39.50 server. The page title,
breadcrumb, and heading should correctly reflect the operation you
perform.

Works nicely and all strings are translatable.
