medmunds 61660cd5ff SparkPost: call HTTP API directly [breaking]
Switch from the (now unmaintained) python-sparkpost
client library to a requests-based backend that calls
SparkPost's Transmissions API directly.

Also adds support for text/x-amp-html alternative parts
(which are supported by the SparkPost API, but weren't
by the client library).

Closes #203

Batch send performance
======================
If you are sending batches of hundreds of emails at a time, you can improve
performance slightly by reusing a single HTTP connection to your ESP's
API, rather than creating (and tearing down) a new connection for each message.
Most Anymail EmailBackends automatically reuse their HTTP connections when
used with Django's batch-sending functions :func:`~django.core.mail.send_mass_mail` or
:meth:`connection.send_messages`. See :ref:`django:topics-sending-multiple-emails`
in the Django docs for more info and an example.
If you need even more performance, you may want to consider your ESP's batch-sending
features. When supported by your ESP, Anymail can send multiple messages with a single
API call. See :ref:`batch-send` for details, and be sure to check the
:ref:`ESP-specific info <supported-esps>` because batch sending capabilities vary
significantly between ESPs.
