the public docear version of cannot extract "real" highlighted text but only text that is stored in "pop-up" boxes

we recently paid a student to enhance docear, so docear could also extract the "real" highlighted text. unfortunately, the student never 100% completed the job (the new function has some bugs, but they relate mostly to Docear not the extraction of highlighted text itself).

if you are interested in using that add-on for JabRef, let me know. Otherwise, you are welcome to just copy the functionality from Docear's public repository on GitHub. https://github.com/Docear

The following things should be extracted:

• notes / highlighted text / comments
• list of contents
• bookmarks

#2545 is merged now, so we can display pdf comments and highlighting.

Hence, I am merging this issue.
