* trustdb.c (uid_trust_string_fixed): Show uids as revoked if the key is
revoked.
* keyedit.c (show_key_with_all_names): Don't show validity for secret key
UIDs.
* keyedit.c (parse_sign_type): New.  Figure out the flags (local,
nonrevoke, trust) for a signature. (keyedit_menu): Call it here so we can
mix and match flags, and don't need "nrltsign", "ltsign", "tnrsign", etc,
etc, etc.
