first minor release after 1.0

Thanks to @Haestan and @bubenkoff for the following fixes:

New stuff:

• Rest Navigator now has automatically built Sphinx documentation which is uploaded to readthedocs.org (#34 by @bubenkoff)
• Navigator.hal now allows passing in an explicit session. This makes using OAuth much easier (#37 by @Haestan)

Bug fixes:

• Embedded documents would re-fetch their state, not properly caching it (#39 by @Haestan)
