Added section about instance variables (properties), including warning about accidentially adding it to the class prototype

| #### WARNING! | ||
| *Do not add the variable accidently to the prototype, by defining it outside the constructor* (Even if mentioned [elsewhere](http://arcturo.github.io/library/coffeescript/03_classes.html#content), this does not work as intended, due to the underlying JavaScript prototype concept). |

Do you want to mention that it only works for primitive properties (= number, string, boolean, null or undefined)?

I wouldn't emphazise on that, since it is only a very special case, and
the constructor-pattern is failsafe.—
