when matching patterns, !rank item++ would not get replied to
since the karma matcher would hit, increment item, and then return
(with no response). now it hits but lets processing continue.
doing !rank item++ of course still increments item, which is probably
not what you want to have happen, but i'm not sure how i feel about
fixing it yet, since even if it's not what you /want/ it's probably
what you /expect/.
when starting another sentence because the main one is too short,
do a bit of work in an attempt to avoid "nick: blah" starts, since
they're fairly common. instead we just ignore nick: and start with
"blah blah"
when starting a second (or Nth) chain because the results so far
are too short, add punctuation to the end of the chain, just to
make things feel a bit more natural
this clarifies a bunch of sections and seems slightly faster
target_word (which would be randomly selected from the input every
time) is replaced with seed_words, a shuffled list from the input.
this is to eliminate accidental reuse of the target word, which
would result in chains like X X X X X X X X X X X X X because
it'd keep targeting X
the rest of this is mostly just debug cleanup, though to simplify
the backwards code it only tries to find one target word
WARNING!
there's no going back now. this change is *huge* but it was overdue.
WARNING!
the database backend is now mysql. modules that should use a database
but don't yet were left untouched, they'll come later. scripts haven't
been converted yet, though i'm pretty sure i'll need to soon.
while i was going through everything, connection/cursor idioms were
cleaned up, as were a bunch of log messages and exception handling. this
change is so gross i'm happy things appear to be working, which is
the case --- all modules are lightly tested.
