The TxRep and AWL tables do not save enough information to do perfectly accurate relearning, but some improvement on sa-awl is in order.

The current sa-awl tool's only functionality is to delete reputation entries that have been hit fewer than $threshold times.

Due to TxRep's reputation diminishing over time, we likely just need a mode where it takes emails from STDIN, rescores them, and applies reputation as if they had just come through the regular mail pipeline. We likely also want a way to forget specific reputations, not just those that are infrequently hit.
