Allow !ops in PM

Currently !ops can only be used in the channel in which the command is called. I believe this can make the user calling ops a target or provoke the troubling user to cause more issues.

It would be good to have getting help in PM as an option (/msg bot !ops #channel) in order to request op attention in private avoiding these two issues. I am not sure how it would work to op side though, would it PM the ops separately or alert on channel anyway, but the current factoid system doesn't seem functional to me.
