Elevators do not work properly

[codexp]

Elevators have same problem as travel-boxes with no update on punch (see issue #27), but they also have one more problem. After reordering all targets seem to be mixed up and names/labels do not correspond to their targets. Sometimes even "<> current" target teleports somewhere else.

Why is such a buggy code even in master branch? I guess it hasn't been tested at all.

Code could also have been tested but not fixed
