Add code linting and formating phase before commit

[jrgcubano]

The idea is to be able to perform some linting and formating before committing your code. The commit phase will break if linting and formatting not working as expected on current staged changes. With this we can ensure no errors (like missing semicolon, etc) and give us some coding style to follow!
