ALIASEDIT kept its aliases in a process-wide store and nothing saved or
restored them, so they were gone after a restart. The engine now gives
the set and the alias file REINIT reads to the host profile
(alias_profile) and restores them (restore_aliases) in CadApp's
profile_json / load_profile, bounded and safe on a malformed saved set;
command names still win. The Command Aliases dialog says where the
aliases are kept.
