image cracking results

I've finally managed to get something working with the Outlook addin and
Skip's cool new ocrad stuff.  the results look promising! :)  A summary of
my results are below.  The runs are 'Tokenizer:x-image_size' and
'Tokenizer:x-crack_images' both set to False, versus both set to True.  It
looks like a 13% improvement in false negatives, which is nothing to sneeze
at!  I've never been an expert at reading these results though, so let me
know if there is anything interesting I missed or neglected to send.

Cheers,

Mark
