Summary: spambayes classification crashes when untrained

Initial Comment:
When classifying a message on a untrained dataset the classification crashes on line 293 in classifier.py with a ZeroDivisionError:

        prob = spamratio / (hamratio + spamratio)

Easiest fix is to test beforehand "if hamratio+spamratio == 0.0" and return a probability of 0.5.
