xfrun4 + dbus

Hello

Benedikt suggested this on the thunar list

Attached is a patch to xfrun4 which first checks if this service is 
provided on the session D-BUS and if so calls OpenDialog("") on it.
Otherwise it falls back to current behavior.

The attached python script when launched provides this interface, to 
test the latency of such a remote launch would be. The dialog is just 
two ugly buttons but that's not important.

thoughts?

thanks
