Summary: tte.py Improved ratio handling

Initial Comment:
If ham and spam are more balanced than the ratio argument (e.g. ratio is 2:1 and spam and ham counts are 150 and 100, the current behavior is to train on 150 spams and 75 hams.  That's really never what you want.  The ratio should delimit the unbalanced-ness.  The attached patch does that.
