Add a Print Cylinder register for cylinder and plate readiness

Tooling was free text on the specification and a manual select on the Work
Order. The register records each cylinder/plate with its specification,
colour station, dimensions, ownership, location, condition and impressions.
Work Order release now reads it: a job needing print tooling is blocked until
every registered cylinder for its specification is Ready.
