@yhwh what is the `browserstack.tunnel` config option for ? It's not mentioned in https://github.com/browserstack/api

You might be using the tunnel even if `bsConfig.startTunnel` is `false` (for instance we do this on Angular build, where we start the tunnel outside of this launcher and run a few Karma builds using the same tunnel).

Is there any reason why this should be `false`?
I'm thinking we should just set it to `true`.
