Code Style: Fixing inconsistencies

I've been playing with [ESFormatter](https://github.com/millermedeiros/esformatter) and used this on QUnit code to fix current inconsistencies in the code style.

It wasn't automatically as I would like to, I got this step by step, reviewing each change. Although, it's not perfect, as I jumped some steps at `test/deepEqual.js` as you can see.

There's no new feature, not even a bug fix here. All should be treated separated.
