cv.tex: Cite UW SWC workshops and order by decreasing date

Using the unsrt style to get citation ordering.  I also sorted entries
in the other sections.  Co-instructors are listed in the order in
which we appeared.

The message-ID comments point at emails describing my role and
collaborators for sections I helped instruct, but I've replaced '@'
with ' at ' to avoid confusing BibTeX.
