Maven integration. #4.

Notes:
- Using the 2.0 alpha version of the jasmine-maven-plugin to maintain
  consistency with Jasmine standalone and jasmine-node versions.
- jasmine-maven-plugin plugin is configured to use PhantomJS, because HtmlUnit
  would not run tests that depended on jQuery with extensive modification.
