Specs without expectations should be alerted to the user

- Add console.error to the HtmlReporter when there is a spec without any expectation
- Change the spec's link text and color to include a warning
- Create a status for specs to label them as "empty"
- console is not accessible to IE unless you have developer tools open,
  so protect against that by mocking console.
