Makes transit tubes a lot faster

Because some people complained that the tubes were too slow to be worth building.
I'm really not sure at all about the numbers and this might be horribly overpowered, so I'm open to feedback.

Also adds a container_resist for the tube pods.

Edit: Shortened time spent stopped in stations as well.
Was this causing problems? src. should be implied.
