View source for Tail-lights container

TS 12 SP1 finally has introduced a native function to use Taillights without needing a custom script.

As before (for script variants), the coronas have to be defined inside the effects container in the mesh-table.

To make those coronas work as tail-lights, a new container type named "tail-lights" has been introduced.
This container has one child element per tail-light, in each child the matching effect name is referenced and the location of the tail-light is defined.

This function shows the backside-coronas of the last traincar in a train, if the last car is not equipped with taillights, no coronas are displayed.
