Adding a Dictionary Sort to MT

I wanted to sort the entries in ‘Enlightened Dreams | Fiction’ by a dictionary type sort — ignoring html, punctuation other than a ‘-’ (including those encoded as html entities), treating whitespace as a single space, and with case insensitivity.

I posted the problem to the MT board, and we kicked it around a bit. Oscarf gave me the right lines to start hacking, and while I was working Staggernation gave some good simpler hacks, that aren’t quite what I wanted. (Simpler to write — the only difference in applying them is if you find, copy, paste once or twice)
