IBC TANK FIX

Unfortunately, a production error has crept into the previous IBC containers.
The manufacturer simply forgot a tap to be able to empty the container in a silo or production.
For this reason, the supplier has been prohibited from further production and sale of the faulty containers with immediate effect.
This mod replaces the previous IBC containers for herbicides and liquid fertilisers with the modernised version with tap. It is now finally possible to use these containers in production.
