Subject: == Python API docs ==

- Enhanced the -T option:

  - we can now choose among custom themes (now 'blender-org' and later 'naiad')
    and Sphinx internal themes (use -h option to see which ones)

  - choosing a custom theme will copy the theme dir to the output dir

- Added two new command line options:

  -N: Add the theme name to the html dir name
      For example, if we choose the theme 'haiku'
      with using -N will create html files in sphinx-out_haiku/
      Useful to test separate themes without overwriting the smae folder each time

  -B: Builds the html docs running sphinx-build
      This is useful to avoid runing sphinx with a separate shell command

- Fixed the URL in undocumented_message()
