Check In - Manifest access permission

A user permission (Check In Manifest - Access) has been added to control access to passenger manifests (and the personal info on them) from the Check In screen. If a user does NOT have this permission granted, he/she will NOT have access to the Working Manifest, Email Manifest, and Pre-Flight List functions - ie. those buttons will be disabled. Users who do have this permission will have them enabled, as was previously the case for all users.
