Point at project page on pypi. Change http links to https.

Limit the travis status icon to just the master branch.

Apparently github and bitbucket lack some of the more obscure RsT
rendering options.

Update docs. Bump version.

Also added some dist_clean dirs to remove and info on using coverage.

Fixed a number of pylint issues - many more to go.  Have to balance
pylint's config with the default Google style conventions.

Info on how to use tox.  Well, just telling people to run tox, not a
huge amount of info there.

Now using reStructuredText. Cleaned up a few text errors.  Added link to
travis test status.
