More work on completing the transition to setuptools.

* Mailman/testing -> Mailman/test
* Removed Mailman/testing/base.py
* Fix mailmanctl by using a different way of calculating where the qrunner
  script is.  The configuration file no longer knows what BIN_DIR is, but the
  mailmanctl script knows where it lives via sys.argv[0].  Also, PREFIX_DIR ->
  VAR_DIR.

Also,

* Since the overwhelmingly predominant use of ILanguageManager is to get the
  description, and since .get_language_data(code)[0] is not very readable,
  split the interface into .get_description() and .get_charset().
* In the setup, automatically add all Mailman.bin modules as command line
  scripts.
