Log Message:
Update to 0.54. Changes:

* New ``--terse-summary'' option to tmda-pending which can be used as
  an alternative to ``--summary''.  See ``tmda-pending -h'' for more.

* New tmdarc options PENDING_DELETE_APPEND and PENDING_RELEASE_APPEND
  which define filenames to which the sender address will be appended
  when a message is deleted or released by tmda-pending.  This can be
  used for example to update your white/blacklist from tmda-pending.

* In addition to ~/.tmdarc, ~/.tmda/config is now a valid location for
  your TMDA configuration file.

* Performance improvements.

* Bugfixes.
