Allow classes to be namespaced with subdirectories

Classes files may now reside in subdirectories, which act as namespaces.
For instance, a class ``ssh.server`` will result in the class definition
to be read from ``ssh/server.yml``. Specifying just ``ssh`` will cause
the class data to be read from ``ssh/init.yml`` or ``ssh.yml``. Note,
however, that only one of those two may be present.
