I forgot to include these in 63eb6672eac794a9c39dec87db3aa45147e06974
(This is fine because noone but me touched these files since the initial
change in db7ef3f02517f9f2a3c56829a22b9fad3c36e374).
Tons of changes. Here's the summary of things that matter most:
* There is no more supybot.fix.
* There is no more supybot.webutils; now there is supybot.utils.web.
* It's no longer webutils.WebError, but just utils.web.Error.
* You shouldn't import itertools, ideally, but instead import utils.iter.
* No more using imap/ifilter in commands unless absolutely necessary. It's
premature optimization and annoying.
* utils.str.format isn't quite ready yet, but will be soon. That'll be the
next big thing to fix in our code.
