[Florian Müllner <fmuellner src gnome org>]

commit 4d43424efdb168face0bb9afe8e0527f09637efb

    Remove source icon when a corresponding window is activated
    
    Source icons are no longer needed to inform the user about events
    having occured in a particular application when (s)he activates the
    window - treat that case just as if the user had clicked the source
    icon.
