[Configobj-develop] Some more work on ConfigObj

[Nicola L. <ni...@te...>]

Some more effort spent on ConfigObj.

Fixed validate doc to talk of ``boolean`` instead of ``bool``; changed the
``is_bool`` function to ``is_boolean`` (Sourceforge bug #1531525). Thanks
to the reporter for this one.

Added a missing ``self.`` in the ``_handle_comment`` method and a related
test, per Sourceforge bug #1523975. Thanks to the reporter for this one too.

Allowed arbitrary indentation in the ``indent_type`` parameter, removed the
``NUM_INDENT_SPACES`` and ``MAX_INTERPOL_DEPTH`` (a leftover) constants,
added indentation tests (including another docutils workaround, sigh),
updated the documentation. Thanks for this one go to Jorge Vargas, even if
I ended up not using his patch that added a new ``indent_size`` parameter.

It is particularly galling to realize that if I bought a new Mac, I would
be subsidizing the development of an operating system that contains code
whose sole purpose is to lock me into a specific hardware platform.
