Fix bug when passing multiple arguments to log

[zant]

hey!

really good playground, super nice, i already switch from jsbin to codepan 🥇

i made this PR because i notice that when calling console.log with multiple arguments, the following error appears in the integrated console:

the error was due to the support of styling logs, i just check if any styling is intended, and if is not, it should return an unstyled text, i also added a blank when joining arguments to have them separated, but i'm not aware of the use case of the previous way

TODO:

• [x] Add support for arrays

please review @egoist @Prozi :)
