Improve handling of long IDs

plotID does not wrap long IDs itself. Since long IDs are only an issue for custom IDs and the position of line breaks is often crucial, line breaks can be easily added by the user inside the ID with "\n". This MR improves the handling of IDs which include line breaks.

Closes #25 (closed)
