Bug 11812 - Add missing "required" indicator to fields which are required

Form fields in the staff client which are required should be configured
to be so by doing several things:

- Add a class "required" to the field's <label>
- Add a class "required" to the form field
- Add 'required="required"' to the form field
- Apppend a <span class="required">Required</span> after the form field.

Several places in the templates are missing the <span>. This patch adds
them.

To test, apply the patch and view the following pages to confirm that
the "Required" text appears:

- Acquisitions -> Add an order to a basket from a new (empty) record.
  Title, quantity, and fund should indicate they are required.

- Administration -> Authority types ->  New authority type. The
  authority type and description fields should indicate they are
  required.

- Administration -> Authority types -> MARC structure -> New tag. The
  tag field should indicate it is required.

- Patron types and categories -> New category. Category code,
  description, and category type should indicate that they are required.
  FIXME: Enrollment period is required but the user must choose one. I'm
  not sure how to handle that clearly.

- Tools -> CSV profiles. Profile name, profile type, and profile MARC
  fields should indicate they are required on both the new and edit
  forms.

- Administration -> Manage MARC modification templates. Under "Create a
  new template" the name field should indicate that it is required.

- Tools -> Batch patron modification -> Submit a batch for editing. Any
  fields which are required according to your BorrowerMandatoryField
  system preference should indicate that they are required.

Patch behaves as expected.

QA Edits: Re-worded the "required" not on the batch patron edit form,
added a missing word to the help text on that page. On the csv-profiles
page I removed an unnecessary "javascript:" protocol from the markup.
