NAWQAAN-242

Added the jasmine-maven-plugin and the saga-maven-plugin. At the moment, I am excluding some of the javascript files as they throw errors in the console which causes the tests to fail when running with a headless browser. Once this has been merged, I plan on creating a jenkins job to perform the sonar analysis. This uses the results of the saga-maven plugin.
Or is it a property set by the phantomjs-maven plugin?
