PR: Changes for Jasmine 2.0.1 - tracking total expectations, passed expectations, failed expectations

Hey again @detro

Jasmine merged in my PR [jasmine#575](https://github.com/pivotal/jasmine/pull/575) for [jasmine-2.0.1](https://github.com/pivotal/jasmine/blob/master/release_notes/2.0.1.md#features).

I've included some small changes for JSReporter2 to bring it in-line with jasmine 2.0.1
