    connect_after to the UpClient::changed from the power plugin
    
    This lets the xrandr plugin, which is the other user of UpClient::changed, to run
    its signal handler *first*.  By the time the handler in the power plugin gets called,
    all the RANDR outputs will be configured correctly and the power plugin will
    be able to make its decision about whether to suspend the machine or not.
    
    Doing this with signals instead of an async DBus calls simplifies things,
    and removes the scary/racy asynchronicity of suspending vs. reconfiguring outputs.
