Subject: First cut at a rules processor, separate from the disposition of rule
 hits. The basic idea is that we process rules on a mlist, message, metadata
 triplet making a list of all rules that hit.  Then a different part of the
 system will decide on the disposition of a message based on which rules hit
 and their priority.

The doctest and plugin architecture is in place, including the tie-in to
setup.py.  Ported the first rule -- emergency.py -- to the new rule
processor.

We no longer need SQLAlchemy as a requirement, and the setuptools/bzr plugin
name has changed.
