    Fix leak of GSource objects which causes performance problems
    
    The GLib event loop scales poorly as the number of GSource objects
    increases. A missing unref on the GSource objects used in the VNC
    connection meant that many unused instances accumulated, slowing
    down the event loop processing.
    
    * src/vncconnection.c: Unref all GSource objects
