New tests for prepared statements:
- 'ps_10nestset' uses a "nested set" approach for an employee hierarchy, then does arithmetic on the "salary" field; (soon) to be extended by inserts / deletes which imply mass updates on the "l"/"r" fields showing the set inclusion, - 'ps_11bugs' will get (some of ?) those bug DB entries which refer to prepared statements, but whose number does not appear in a test file comment - so it will also be extended.
