Use spaceship names as their surface names

Primary motivation for this change is to have the turret alerts be more informative. You would at a glance see which of your ships are flying, rather than have to look through all of your ships in the universe explorer.

Changing surface name when a ship gets (re)named should be fairly straightforward. We would need to make sure the name is unique. I'm not sure if SE currently reserves surfaces names for all of its zones on initialization. If it doesn't, then we would also need to make sure the new name doesn't match any surface names that a zone would have wanted to use.

The real challenge will be to make sure this doesn't break any other part of Earendel's mods that expects surface names to be immutable.
