Map editor deletes definitions under wormholes

[beccabunny]

It seems that, currently, if a wormhole has a description or spaceport the map editor automatically removes them

Very much related to #14

I have a done a non-trivial amount of work to support it already, but have generally not had time to move it forward in the past 2-3 years. In the 0.9.13-0.9.14 review period I'm hoping to finish it up.

My solution to this issue has been to just make the spaceport and description of wormholes x; the map is deleting these lines because we're leaving them empty.
