MTR U-Bahn Wien Pack

Changelog:

• added "panto high" and "panotless" variants of the Type T Car
• "panto high" = pantograph is 0.5m higher than the normal "panto" version
• "pantoless" = pantograph is lowered, not higher than the rest of the roof

• fixed a Type X Car texture issue reported, should work correctly now

• added another variant of catenary pole for the normal "panto" height of the Type T
