create bidirectional mapping between PDF comments and i-librarian user-comments #2

When exporting a PDF, if PDF notes are selected for inclusion, these should be mapped to sticky-notes (or some other PDF standard annotation) in a way which allows identifying each user, and also allows importing such a PDF back into i-librarian. When importing a PDF like this, i-librarian should have a way of allowing the user to peruse all comments, and modify if desired who a comment is attributed to, or whether a particular comment is imported.

PDF notes are added as standard PDF comments in 3.0. Author names are missing though. This should be easy to implement.

Importing PDF annotations is not planned, because I don't know how to read them. Suggestions about how to extract annotations with PHP, GS, Poppler, Pdftk, or some other crossplatform tool are welcome.
