edit: Teleport planes and land units to carrier on load

Edit lets deities load units onto remote carriers, resulting in a
carriers having cargo in another sector.  Not good.  Cargo gets
teleported to its carrier belatedly when the carrier moves.

Better let edit take care of the teleport.

Also tell the deity that he just caused a teleport.  Necessary to give
the deity a chance to catch unexpected changes, e.g. a player moving a
plane right before the deity edits it.  Watching out for such changes
is especially important with non-interactive edit.
