    Move style updates in AppIcon._onStateChanged out
    
    There is currently no simple way to inject into AppIcon's state change,
    so an extension that wants to do this has to destroy/remove/update all
    icons in the Shell (i.e. in the Dash, AllView, FrequentView) on enable()
    and disable() after updating AppIcon.prototype._onStateChange, or the
    extension must require a restart of the Shell.
    
    To solve this issue, we rename _onStateChanged to _updateRunningStyle,
    and connect the notify::state signal with an anonymous function that
    calls _updateRunningStyle.
    This extra function call should allow extensions to just extend the
    updateRunningStyle function in the prototype.
