CRLF bugs back in 0.15.*

[Allyn Fratkin]

hi everybody.

i've been using bogofilter 0.14.5.4 for awhile.  my first try with
bogofilter 0.15.* (specifically 0.15.10) was a disaster
as CRLF is no longer recognized as a line separator.  this
causes the same old behavior from around the 0.7 days where
mime is not discarded (and subsequently causes extreme swelling
in the word list) and message separators are not recognized.

so instead of something like this:
# 166480 words, 8635 messages
i got this instead:
# 5936000 words, 15 messages

i'll start to dig into the code but perhaps someone that knows it
better can fix it more quickly and more thoroughly than i can.

thanks.
