Upgrade to tmda-0.64:

* New feature. TEMPLATE_DIR_MATCH_SENDER provides a way to further
  specialize the template selection process. When enabled, TMDA looks
  for templates in a subdirectory of TEMPLATE_DIR that matches the
  sender address, and then increasingly general portions of the domain
  part of the address. For more information and an example, see
  <URL:http://tmda.net/config-vars.html#TEMPLATE_DIR_MATCH_SENDER>

* tmda-pending now allows messages to be specified on standard input
  instead of the command line by using `-' instead of a message
  list. See ``tmda-pending -h'' for an example. Thanks to Michael
  S. Fischer for the patch.

Only accept Python 2.2, as the PLIST is incorrect for 2.1 (due to one
file failing to compile).
