Subject: Add pluggable components.

 - Adds the notion of a 'plugin'.
   - A plugin has a package path and a flag specifying whether
     it's enabled or not.

 - Adds a find_pluggable_components function similar to the
   find_components one. This one dynamically searches not only
   the mailman package but all of plugins.
   - e.g. find_pluggable_components('rules', IRule) finds
     all IRule components in mailman.rules but also in
     example_plugin.rules for plugin names example_plugin.

 - Uses the find_pluggable_components function in place of
   find_components when searching for Rules, Handlers, Chains,
   EmailCommands, and Styles.
