Shipping Container for Brio (fully compatible)

This modifies the original great design to improve compatibility with the Brio freight system:
1. The height was scaled down by 2mm so it will fit into Brio freight ships and wrapper containers.
2. The pinholes have been increased to a radius of 4mm to work on all trucks and freight cars without having to use a drill to increase the sizes of the holes.
3. The mesh itself got fixed on the way as well.
