Changed the runTest() method to return a promise.
Also updated the pattern which matches the name of the Sauce Connect logfiles in .gitignore.
Created a scheduler limiting the number of concurrent running promises. Changed the code to use this scheduler for throttling the concurrent jobs.
Jobs are started separately for each url/browser combination.
Set the throttled option in the Gruntfile for the saucelabs-jasmine so throttling can be tested.
