Refresh Train Depot HUD After Editing Train

[Phelzier]

I have a train with two locomotives facing the same way. After editing the train and flipping the end locomotive to face the opposite way, the HUD did not reflect these changes. Closing the HUD and reopening showed the locomotive in the correct direction.

This is probably the same bug as voxeltycoon/bug-tracker#24, I think it would be better to move this to a comment on that one and close this one.

Also please use the bug report template in your future bug reports.

added to voxeltycoon/bug-tracker#24. Also description seems similar to closed issue voxeltycoon/bug-tracker#34

@Phelzier @polak-jan yeah, it's more close to voxeltycoon/bug-tracker#34. However that was fixed, so it's probably a new bug, reopening.
