* Introduces a new directory called `util` in the gulp setup. This should make the gulp setup more clear and maintainable.
* The utility `task_helpers` no longer includes random utilities like for Firebase. Those have been moved to their own util file (similar as in `e2e/`)
* Refactors the Github Status utility because it can be useful for other things as well (e.g upcoming coverage, payload)
