Add inline note interface
Original patch by Michal Srb.
The inline note interface provides a way to render arbitrary things in
the text. The layout of the line is adapted to create space for the note.
Possible applications include showing a name of a function parameter on call
side or rendering square with color preview next to CSS color property.
