Remove a whole chunk of needles that haven't matched for more
than 3 months. Also move a few needles to appropriate locations,
simplify some code chunks that relied on removed needles (if
we're not matching the needles, we don't need those chunks any
more), and drop some other no-longer-needed conditionals for
older releases.
