Teleporter mapping enhancement

![](https://i.imgur.com/yBMRwyn.png)

Allows teleporters to be mapped in any direction. Set the dir of the teleporter computer to the direction that the hub is in. I.e. if the hub is east, set the teleporter computer dir to 4 (east).
Applies underlays and overlays to the components to correctly align the connecting cables.

The teleporter computer will now also set up refs for the hub and station at initialization so we don't have to search for the other teleporter components every time we teleport!
