Bug 15925: Correct some markup issues with patron lists pages
This patch makes some markup changes to the patron lists interface in
order to make them more consistent with other areas of Koha.
Change to look for when testing:
Tools -> Patron lists:
- Wrap "New patron list" button in standard <div id="toolbar">
- Place toolbar above page heading.
Tools -> Patron lists -> New patron list:
- Use built-in form validation for required fields
- Clarify page title and breadcrumbs on list add and edit
Validation errors have been corrected on all three templates, including
removal of an extra </div>.
