Subject: AGI: Stop set.simple getting called for <2.425

Also stop it from getting called by 2.440 AGI.
Was implemented for 2.425, removed in 2.440 and re-added
in 2.917.
The opcode is called after answering the phone at the store
(555-6969) in Apple IIgs Larry. It can't be automatic saving.
See script 22, line 678 in AGI Studio.
Stops automatic saving getting enabled for Larry 1 Apple IIgs.
Also added warning messages to other commands as well.
