Rewrite Spec & allow Jasmine to be namespaced

- THere seems to be a performance regression. Large test suites may
  throw
- Regressions: Mock Clock won't install correctly, async specs are
  temporarily not supported.
- Async spec runs/waits interface is gone. Blocks are gone.
- Move most global usage into jasmine.Env constructor.
- Remove optional 'Jasmine running' from HtmlReporter -- caused
  NS_FACTORY_ERROR in firefox when tested
