Standardize code

[plribeiro3000]

This repo does have a rubocop file with the fog standards. But if you run rubocop you will get 97 files inspected, 1033 offenses detected so i believe we have to fix this before it get even bigger.

We need to add rubocop back and follow the fog standards.

This change breaks our standard and we need to fix it asap.

@plribeiro3000 Ah, sorry about that. I was making some adjustments so that TravisCI would pass for all the available versions. I had meant to temporarily remove rubocop for testing purposes as it was causing a failure and forgot to add it back so I could identify the cause of the failure. I can add it back, but will still need to investigate the issue further.
