Fix the docs run failing on Travis

Likely that the deprecation warning from cryptography is causing the
setup.py sphinx build command to return an error so the tox/travis job
is marked as failing. Changing to calling the sphinx-build command
directly solves this.

Also updated the sphinx config for built-in napoleon and faster builds
using jobs option.
