    Better control of when to allow variable monitoring
    
    	* src/persp/dbgperspective/nmv-var-inspector-dialog.cc
    	(VarInspectorDialog::Priv::on_var_name_changed_signal): Do not
    	enable/disable the "add to monitor" button based on the presence
    	of an expression/name in the "variable name" entry field.
    	(VarInspectorDialog::Priv::on_variable_inspected): Enable the "add
    	to monitor" button only when the expression has been inspected.
    	(VarInspectorDialog::Priv::on_variable_inspector_cleared): Disable
    	the "add to monitor" button when the inspector has been cleared.
