Cleaning up the QPainter/arthur testing stuff

This removes various remains of historical test tools, and the entire
tests/arthur directory. The living parts are now:
tests/auto/lancelot  - including the suite of qps scripts. The
                       script engine now lives here.
tests/baselineserver - moved to toplevel since not arthur-specific.
tests/manual/lance   - for manual running and editing of qps scripts.
