Add option to include "Patch" info in top tickets by weighted vote reports

I won't actually include them in the reports yet.  I was hoping it
would help give a quick indication of whether the ticket needed work
or not, but that would be better indicated by including info about
whether it has a prescreened patch, which would take more coding than
I want to do right now.

Also remove commented-out use of clojure.edn.  I'm sticking with
clojure.tools.reader.edn.
