I simply want a memory of how a specific message was trained, for the
following reasons:

* Accidental attempt to train the same message, in the same way, multiple
times.
* Accidental attempt to train the same message as ham and spam.

It really is as simple as that.  Note that we *could* store this information
with the message itself - but this would mean that a simple train operation
*modifies* messages.  This allows us to keep training as readonly wrt the
messages, while maintaining integrity.
