Updating Jasmine-Node to latest Jasmine

I see that 1 year ago you committed `jasmine2.0.0-rc1.js` noting that if Jasmine accepted your PR then you'd update jasmine.js. I couldn't find a PR on the [pivotal/jsamine](https://github.com/pivotal/jasmine/pulls?direction=desc&page=1&sort=created) PR list for you, and since it's been a year, I figured that whatever issue has probably been worked out. I tested this in conjunction with my other PR and all unit tests pass/fail at the expected rate. At first glance it looks like this merge should be fine.

I also tested the new version of jasmine on a few of my projects inside of jasmine-node and they all appear to work as well.
