extended commit (see note)

- Slight overhaul of init() system; added ``edbob.init_modules()`` function.

- Added ``read_service()`` method to ``AppConfigParser`` class, for use with
  Windows services.

- Added generic ``Service`` class to ``edbob.win32`` module.  (File monitor now
  inherits from it.)

- Tweaked ``edbob.db`` initialization somewhat.  (``Base.metadata`` no longer
  binds to ``edbob.db.engine``.)

- Fixed guest role bug in ``edbob.db.auth.has_permission()`` function.

- Added "automagical" enumeration support for database extensions.

- Added ``EMAIL_PREFERENCE`` enum to ``contact`` database extension.

- Tweaked ``edbob.pyramid.includeme()``.

- Tweaked ``people`` Pyramid views.
