Well Wagon, Motorail Wagon and Coil Wagons Bug Fix

Trainz 2022 SP5 was recently released. Amongst other things, this changes the system that's used to load commodities into rolling stock. This new system does not allow for one commodity to be placed in more than one load queue when loading, while the old system did.

This impacted three of my models; the well wagon, the motorail wagon and the coil wagons. Each of these had three queues with 1 spot in, to allow them to be loaded in a variety of different ways. But this new load system means you can't load the same thing twice.

As such, all three of these models have now been updated with a new load queue, load_triple, which can take 3 of a single commodity. As such, this means these wagons can now be fully loaded under the new system.
