[NTG-context] Removing the quotes from the results of the reference links

[Alan BRASLAU]

I have:

\setvariables [Book]
                [
                title={My title},
                subtitle={My subtitle},
                author={First Author, Second Author and Third Author},
                ]
\setupinteraction
                [
                title=\getvariable{Book}{title},
                subtitle=\getvariable{Book}{subtitle},
                author=\getvariable{Book}{author},
                keyword={keyword1, keyword2, keyword3},
                ]


and this yields (in acroread 9):

Title: My title
Author: "First Author, Second Author and Third Author"
Subject: My subtitle
Keywords: keyword1 keyword2 keyword3


So, quotation marks (" ") get put around the author;
The subtitle becomes the subject;
and adding the trailing comma after keyword={},
indeed removes the {} but also removes the explicit commas.
