Configuration

-------------
 * `[passlib]path` configuration variable renamed to `[passlib]configuration`.
 * Postfix-specific configurations in the `[mta]` section are moved to a
   separate file, named by the `[mta]configuration` variable.
 * In the new `postfix.cfg` file, `postfix_map_cmd` is renamed to
   `postmap_command`.

Also:
 * More Python 2.7-isms, use assertMultiLineEqual() directly.
 * Added external_configuration() and load_external() to mailman.config.config
 * ConfigLayer does a blanket set of [postfix]postmap_command so subtests
   generally won't have to.
