make /ooc the default when no slash command

When no slash command is given (i.e., text without a starting slash is
posted), treat is as an /occ slash command. I'm really not sure this is
the best thing to do, but I do no requiring the slash is too confusing.
I think more work will have to be done to make using slash command
intuitive.
