Bump version to 1.4.1. Update readme.

Add support for ca_certs and client_cert. Bump version to 1.4.

Note the new constructor kwargs in the release notes.

Don't crash when the query_params kwarg to send_request is omitted. Fix 

#173.

Keep the null value of the kwarg as None for two reasons: (1) so we don't invalidate the docstring which says we can pass None and (2) because mutables as kwarg default values are asking for trouble.

Update AUTHORS file.

Bring changelog up to date.

I accidentally did a release from my own repo (1.2.1). That’s why 1.2.2 introduces commits that actually predate the ones in 1.2.1.

Make sure the Content-Length header gets set when calling `create_ind…

…ex()` with no explicit `settings` arg. Fix #166. Bump version to 1.2.

Autogenerate PyPI page. Stop repeating things in README.

Swap some header types around to make that possible.

Add Python 3.4 to tox config and trove classifiers. All test now pass…

… in all tox envs.

Bump version to 0.6.1, and update changelog.
