Changelog:
21.06.13 - elevator stations are sorted by height instead of date of creation as is the case with travelnet boxes
- elevator stations are named automaticly
20.06.13 - doors can be opened and closed from inside the travelnet box/elevator
- the elevator can only move vertically; the network name is defined by its x and z coordinate
13.06.13 - bugfix
