#775 Provide autowrapping for comments, if line length indicator is active

[Erik Hänel]

Provide an option and functionality to handle the line wrapping of (documentation) comments, if the user activated the line length indicator (like in MATLAB). Should be active, if the user adds a character somewhere in a comment line. If a character is removed, it should not do anything. Style has to be copied from the previous line (keeping documentation comments).
