remove addheaders()

[Tieske]

please remove this, and update the addheader function to detect whether the first argument is a table, if so, add multiple headers, if a string, add a single header.

I agree with you. Thanks, @Tieske
Next release will update with this solution :)

No longer feasible, since it has been out for too long, it would break backward compatibility. Closing this.
