Bug 14358: Changing the module refreshes the page and resets library choice

This patch makes an incremental change towards fixing Bug 14358: The
"New notice" button is converted to a dropdown button which asks the
user to select a module to start with.

To test, apply the patch and go to Tools -> Notices. Test the "New
notice" button and confirm that module selections are reflected in the
notice add form you are shown.
