More updates to rules and chains, especially by adding additional tests.

- Remove the Emergency.py handler.  This is now covered by the emergency.py
  rule.
- Remove the hold.txt doctest.  This is now covered by the chains.txt and
  emergency.txt doctests.
- Added a chains.txt doctest.
- Extend the pending db to handle list values, although only lists that
  contain nothing but strings.
- Rename the 'adminapproved' message metadata key (for the emergency rule) to
  'moderator_approved'.

Also, backport a change to the Decorate handler where message metadata on the
'decoration-data' key ca be used in the header and footer.
