    Support variable value editing in LocalVarsInspector2 (Closes: #581169)
    
    	* src/persp/dbgperspective/nmv-local-vars-inspector2.cc:
    	(LocalVarsInspector2::Priv::init_graphical_signals): Install the
    	Priv::on_cell_edited_signal slot.
    	(LocalVarsInspector2::Priv::on_tree_view_selection_changed_signal):
    	If the selected variable is editable, then make the cell editable.
    	(LocalVarsInspector2::Priv::on_cell_edited_signal): New slot.
    	Assign the variable according to what the user typed.
    	(LocalVarsInspector2::Priv::on_variable_assigned_signal): New slot.
    	Graphically update the variable value upon assignment.
