Added expect(0) to make tabs and tooltip tests pass, even though those assertions are actually missing.
Introduces dialog and slider failures when running in composite all.html suite, all green when running one by one, also all-active.html is green.
The various updates to the unit test suites introduced 0 regressions due to update of QUnit, however the addition of jquery.ui.dialog.css to the dialog test suite did introduce one regression, to the dialog option height tests.
Also removed some old crufty woefully incomplete unused and rotted test harnesses.
