cas 4.7.x-2.1

This release adds some new features to the cas module, including:

• A login menu item for placing a smart login link in any menu. (like primary or secondary links)
• Feature for disabling the change password function on the user/edit screen.
• Feature to disable the users ability to change their email address.
• Login links and blocks now remember the initial page of a user and always redirect them to the page they were on.
• When using drupal as the user repository, newly registered users get redirected to the user/edit screen at first login only (so that they can edit their preferences).
