Ship broking "Buy Ship" actions are all disabled because none of the VOTG ships have access to the <CanUpgradeTo> or <CanUpgradeFrom> events. (Well, maybe. I'm not real sure but adding the events to mod playerships fixed it.)

EDIT: Anonymous32 and PM already spotted this.

2ndEDIT: This error is showing in the debug log when entering ship brokers. 1.0a6/1.8b4.
