Correct Sauce Labs integration

`jasmine-jsreporter.js` is required to let Sauce Labs' unit testing voodoo read the results of Jasmine tests.  Bower no longer seems to be in use to manage this dependency, so I referred to the in-repo version.

Also removed secret keys, you might want to change them (https://saucelabs.com/account, click "Generate a new access key") then keep 'em in the Environment.

Voodoo now fully functional :smile_cat:
