save the current status text for each pane inside wxStatusBarPane: native controls now store the (eventually) ellipsized version of the string; remove code for managing the status strings currently inside the [native|generic] control; add ellipsization support under wxMSW; now that all SetFieldsCount() implementation rrely on wxStatusBarBase::SetFieldsCount document how it behaves when adding new panes.
