Bug 11019 - Require some fields when adding authorized value category

This patch modifies the form for adding an authorized value so that
the category is a required fields.
Previously a new authorized value category could be saved with no data.

To test, apply the patch and go to Administration -> Authorized values.

- Click the "New category" button.
- Click the save button without filling in the category.
  You should be prevented from submitting the form.
- Verify that filling in the required field allows the form to be
  submitted.
- Perform the same test when editing an existing authorized value.
