Print First Header instead of PageID

[joda55]

Feature Description

Currently ACK listing displays ugly page IDs instead of well-formatted titles (employees_policy_it_global instead of IT-Security Policy for Employees). Currently I do apply the following patch after every update, maybe you'd like to include it in the code base. However if someone really likes ugly page IDs, maybe adding a config flag would be a smart solution?
