(This particular case happens when the user cancels
the progress dialog while loading symbols before the
symbol picker has been displayed. 3.5K people have
done this 13K times on MSW.)
Recommendation is to avoid using the year nomenclature as this

Also updates AUTHORS.txt from current repo with contributor names
Also fixes a bug where a single symbol library wasn't expanded
due to the presence of the "-- already placed --" and
"-- recently used --" pseudo-libraries.
