Large Cowshed with Internal Manure Storage

This large cowshed is available with or without a feeding robot. Manure can be unloaded via the manure trigger, and the feed storage has been enlarged.
While not entirely realistic, this modification addresses the manure heap issue that Giants has not yet resolved. Manure is now collected internally in the stable (invisibly) and can be stored using the same trigger as the manure. The manure storage has a capacity of 250,000 liters.
The manure production rate remains unchanged.
Note: Currently, the manure storage level is not displayed in the info window. If someone has the knowledge to implement this, feel free to share tips!
A pig stall version may follow soon.
