    Factorize the support for updating unfolded variables
    
    	* src/persp/dbgperspective/nmv-variables-utils.[h|cc]:
    	(update_unfolded_variable): New function.
    	This function can update the graphical node of a variable that got
    	recently unfolded i.e., that recently gained member variables.
