Flattened class heirachy. No classes now descend from TWebService except TDDabStdWebService. Therefore the methods of TWebService were merged into TDDabStdWebService. Virtual methods of TWebService were combined with their overrides in TDDabStdWebService while other methods of TWebService were simply copied into TDDabStdWebService. TWebService was removed and TDDabStdWebService changed to descend from TBaseWebService.
