Get preprocessor output without line numbers

For easier comparison of  the original source with a doxygen preprocessed source the line numbers can be a bit of an obstacle.
To remove the line numbers in the preprocessor output the option  `NoLineno` has been added.
(In case `Preprocessor` is not invoked, `NoLineno` has no effect).
