- Generated application differences: ``make_app`` entry point

    renamed to ``app`` in order to have a different name than the bfg
    function of the same name, to prevent confusion.

  - Add "options" processing to bfg's ``make_app`` to support runtime
    options.  A new API function named ``get_options`` was added to
    the registry module.  This function is typically used in an
    application's ``app`` entry point.  The Paste config file section
    for the app can now supply the ``reload_templates`` option, which,
    if true, will prevent the need to restart the appserver in order
    for ``z3c.pt`` or XSLT template changes to be detected.

  - Use only the module name in generated project's "test_suite" (run
    all tests found in the package).

  - Default port for generated apps changed from 5432 to 6543
    (Postgres default port is 6543).
