autorespond_requests "w/discard" ignored

[Donnc]

Gui/Autoresponse.py makes a distinction between
autorespond_requests == 1 or == 2, but that's implemented in
the MailCommandHandler.py module, which is unreferenced in b3
and gone in b4. CommandRunner._dispose could check for this
after it calls Replybot.process(), I think. Or if the feature
was intentionally left out, it could be left out of the web
interface too.
