Fix saving and loading of vessel-specific settings

When loading a craft file in the Editor, there's no vessel name
available; thus, all vessel-specific settings (those with persistent
pass TYPE) get loaded at their default values. A few seconds later,
those get saved (with the ship name at the top of the screen),
overwriting any previously vessel-specific settings with their default
values.

Since there's no way to get a ship name in the OnLoad method (it gets
called before the Editor has set the name from the .craft file), the
best option is to simply not save the settings from inside the editor at
all.
