FS22 - Contractors Can Unload Productions V1.0

If the wage earner status is assigned to a farm, this farm can also unload production from the other farm (e.g. BGAs).

Small script, which probably fixes a bug at Giants. It's at least submitted to Modhub, but is still being reviewed by internal developers.

The Abtank symbol for a foreign BGA appears with the status of the wage earner, but cannot be used. This is fixed with this script.
