Add framework for simplemocha and karma tests.

Framework is there for adding tests now. Added a couple basic API tests, but haven't got any Angular tests working yet. Run ```grunt test``` to test.

To do:
- Add actual Angular tests to break-controller-test and break-service-test
- Add more API tests as we do more REST requests
- Add JSHint to test task
