Parallelization: done; there's more work to be done yet.

I made all things parallel which is awesome! Looking at the stdout I feel like we need to do a little more work on the logging before we merge this though. Due to parallel execution it's really hard to now what's going on now.

Keeping this pull request open until I got the change to commit improvements to the logging. We should probably make this a 2.0.

One more thing: Sauce Connect tunneling is now optional.

@axemclion: do you mind giving it a shot using jasmine?
