[Spambayes] 2nd run with received lines

[Brad Clements]

I added this option:

[Tokenizer]
mine_received_headers: True

and did the run again.

I would like to see the change in stdev per run from one run to the next. I think reducing 
the stdev is also a win. I'll see if I can tweak rates.py and cmp.py to extract this info.
