Fix typo in README.
Don't change the checked property of radio buttons

When cloning radio buttons to get the string value, some browsers such as
PhantomJS uncheck one of the radio buttons. Fix this by letting elementToString
use outerHTML instead of cloning to obtain the HTML.
Fix style
v1.5.92
Run tests off of jasmine v2.0.0-rc3
Compatibility with jasmine 2.0

- Jasmine 2.0 doesn't allow you to grab the existing matcher and
  override it, so the matchers that did that had to be re-worked.
- toBe is now a customEqualityTester so:
  - toBe($('.foo'))
  becomes:
  - toEqual($('.foo'))
- toContain was renamed to toContainElement
