This first part of the testing framework upgrade:
- enhances the jsdoc script to allow switching to debug mode from the command line
- uses Jasmine to run tests
- adds flexibility to run tests from multiple root directories
- does automatic test discovery, so test files can just be created, dropped in an appropriate folder, and run without having to explicity add it to the test runner
- cleans up the test directory layout
- incorporates env.rhino.js which should make it easier to test templates
- is incomplete: this is just a savepoint. About 1/3 of the tests have been converted. The rest are still run through the old testrunner
