process_messages: Take "sleep" command from owner
process_messages: Take "sleep" command from owner

If the user defined as the bot's owner in the cfg file sends a
message with the subject "sleep" (body text doesn't matter), the
bot will sleep for 10 seconds. This is useful if a ^C is needed
for some reason, and this replaces having it sleep after every
10th run.
