Updates MembershipHelper to not change the email/name if the value has not changed. Updates the templates to show only validation summaries for their own values/prefixes. Fixes some underlying MVC methods that merge view state to ensure the prefixes work with validation summaries properly when not showing property level errors. Updates the Umb controllers to add model level validation msgs when failed.
