Xml parser with author and csv creator

[DavidSlivka]

Hi, I have created 2 scripts. "add_author_information.py" adds author, author mail and date of an error into a new copy of the XML file. This XML file is generated by cppcheck. The second script "create_csv_with_author.py" takes the output from the first script and makes a CSV file with all the information in XML. I believe some developers may find these scripts useful.
