execute_query now refactored, returns reliable results, does
zero presentation-layer crap. Arguments reduced, client scripts
adapted to new API and performance improved. Text::CSV now used
to generate CSV output, ensuring portability, encoding and accuracy.
Replaced tools/runreport.pl with misc/cronjobs/runreport.pl:
~ security fixed
~ documentation improved
~ TODO: finish sendmail option.
Bug 3077 also fixed.
