python-github3: Use stable release, clean depends
python-github3: Use stable release, clean depends

The former version packaged was 1.0.0a4.  However, 1.0.0a4 is in fact an
alpha release despite being tagged in the upstream Git repository and
being available on PyPI.  This update reverts the package to 0.9.6, the
latest stable release.

The project's PyPI page lists pyOpenSSL, ndg-httpsclient, and pyasn1 as
dependencies.  grepping github3's repository reveals that none of these
libraries are ever imported.  As such, they have all been removed from
the template's depends.
