An attempt to sanitise the directory handling in the test harness. This should allow the test harness to be called from anywhere and uses the location of  testharness.py (assumed to be in a 'tools/' directory of the fluidity source tree) to determine the root directory of the fluidity source and from there determine where tests/ , longtests/ , and examples/ can be found.
