edit: Report flags change properly

Browse source 
Print a message, send bulletin to owner.  Affects ship key 'W', land
unit key 'W', and plane key 'f'.  The message is necessary to give the
deity a chance to catch unexpected changes, e.g. a player modifying
retreat conditions right before the deity edits them.  Watching out
for such changes is especially important with non-interactive edit.
