Update py-sphinx to 1.0.1

* Support for domains has been added.  A domain is a collection of
  directives and roles that all describe objects belonging together,
  e.g. elements of a programming language.  A few builtin domains are
  provided:

  - Python
  - C
  - C++
  - JavaScript
  - reStructuredText

* The old markup for defining and linking to C directives is now
  deprecated.  It will not work anymore in future versions without
  activating the :mod:`~sphinx.ext.oldcmarkup` extension; in Sphinx
  1.0, it is activated by default.

* Removed support for old dependency versions; requirements are now:

  - docutils >= 0.5
  - Jinja2  >= 2.2

* Removed deprecated elements:

  - ``exclude_dirs`` config value
  - ``sphinx.builder`` module

Features added
--------------

* General:

  - Added a "nitpicky" mode that emits warnings for all missing
    references.  It is activated by the :option:`-n` command-line switch
    or the :confval:`nitpicky` config value.
  - Added ``latexpdf`` target in quickstart Makefile.

* Markup:

  - The :rst:role:`menuselection` and :rst:role:`guilabel` roles now
    support ampersand accelerators.
  - New more compact doc field syntax is now recognized: ``:param type
    name: description``.
  - Added ``tab-width`` option to :rst:dir:`literalinclude` directive.
  - Added ``titlesonly`` option to :rst:dir:`toctree` directive.
  - Added the ``prepend`` and ``append`` options to the
    :rst:dir:`literalinclude` directive.
  - #284: All docinfo metadata is now put into the document metadata, not
    just the author.
  - The :rst:role:`ref` role can now also reference tables by caption.
  - The :rst:dir:`include` directive now supports absolute paths, which
    are interpreted as relative to the source directory.
  - In the Python domain, references like ``:func:`.name``` now look for
    matching names with any prefix if no direct match is found.

* New builders:

  - Added a builder for the Epub format.
  - Added a builder for manual pages.
  - Added a single-file HTML builder.

* Extensions:

  - Added the :mod:`~sphinx.ext.viewcode` extension.
  - Added the :mod:`~sphinx.ext.extlinks` extension.
  - Added support for source ordering of members in autodoc, with
    ``autodoc_member_order = 'bysource'``.
  - Added :confval:`autodoc_default_flags` config value, which can be
    used to select default flags for all autodoc directives.
  - Added a way for intersphinx to refer to named labels in other
    projects, and to specify the project you want to link to.
  - #280: Autodoc can now document instance attributes assigned in
    ``__init__`` methods.
  - Many improvements and fixes to the :mod:`~sphinx.ext.autosummary`
    extension, thanks to Pauli Virtanen.
  - #309: The :mod:`~sphinx.ext.graphviz` extension can now output SVG
    instead of PNG images, controlled by the
    :confval:`graphviz_output_format` config value.
  - Added ``alt`` option to :rst:dir:`graphviz` extension directives.
  - Added ``exclude`` argument to :func:`.autodoc.between`.
