Minutes module hook_minutes_event_attendees has changed

The format of the return value for $op = 'title' in hook_minutes_event_attendees has changed with the Drupal 6 version of the Minutes module.

This change was made after Excluded users 6.x-1.0 was released.

In case there are further changes that need to be made, I'm not going to release a new version for a week or two. I've attached a patch that will update the module to work with the new Minutes module.
