Check whether we should ignore the event and mark the control as being dirty if necessary in a virtual method, which can be defined in wxTextEntry and overridden by wxTextCtrl, instead of doing it in GTK callback itself. This will allow to reuse wxTextEntry callback for wxTextCtrl too in the upcoming commits. No real changes so far.
