Part of Bug 17228: console.{log,warn,info,error} should support format
        strings, variable arguments

        Console now takes care of calling ChromeClient::addMessageToConsole
        for the appropriate messages (i.e., just messages from JavaScript). If
        you ever want to add a message to the console, Console is the place to
        do it.
