Guts: We have had enough of these diamonds, ampersands, numerals, snakes, etc.

Figure hey, this template isn't long for this world anyway, and since we aren't
trying to keep it in sync with the main website anymore, we can go ahead and axe
some longtime nuisances.

- No more diamonds in our unordered lists!
- No more poncy ampersands. ("Ampersands.js," can you even believe that, geez)
- Change in-page TOCs from numbered lists to bulleted -- this one was actually
  my fault; I thought numbers looked good for some reason, but it turns out
  they're actually kind of meaningless in this context and they sometimes
  directly contradict the text of the TOC items, so let's say good night to 'em.
