Clean console log

Hi @hd-deman and @park9140,

I think we should clean every `console.log` and use the only when we are working on the code. I don't like to have my code polluted with logs in 'production'

Do you agree guys? Can I delete all these `console.log` :D ?

We can also have an "intern" console.log, and de-activate it if `atom.inDevMode()` is false.
