New engage player reconfigure jasmine

- Reconfigure jasmine and moved the specs into the directory core/js/spec. 
- Added two simple tests for EngageCore.
- Removed jasmine sample specs and js files.
- Updated jasmine dependency
- Resolved an issue with `htmlunit` while running the specs to prevent a `ScriptException`. (Added a few times  `window.console&&` before calling `console`)
```
htmlunit.ScriptException: ReferenceError: "console" is not defined.
```
