Hide clone when token authorization URL is used

I'm trying to figure the best way to use this on Travis-CI. Since there is no authorized user when CI builds are run, I'd like to use 
```js
repo: "https://" + process.env.GH_TOKEN + "@github.com/nschonni/wet-boew-dist.git"
``` 
 
Unforturnitaly this would bleed token to the world :frowning:
