BUG#: 2196
TITLE: Copyright update

DESCRIPTION: Update all .cpp and .h files for new license and
update the doc/license.txt file.  Note that there were also
a couple of files that had to be fixed because they had violated
the comments rules (ex. blank line at head of file or in the case of
xmlwriter.cpp a comment line //=========  which drove the strip
function nuts.  These were fixed.  This has been compiled and tested
on windows.
