* Don't maintain similar overview in README.rst and docs/index.rst -- instead just include relevant portions of readme in the docs
* Patch up README version numbers and doc links in setup.py long_description to freeze them to the version being setup
* Suppress the Travis build status indicator in the docs and PyPI, since it can't be frozen to the specific version in question
Treat image attachments with a Content-ID header as embedded, rather than ordinary attachments. (Rationale is that you must set the content-id to be able to refer to the image within your html, so that's a reasonable indicator to handle it as embedded.)
Introduce djrill.NotSupportedByMandrillError for unsupported functionality (previously used generic ValueError).
Change to djrill.MandrillAPIError, derived from requests.HTTPError, for API error responses (previously used djrill.mail.backends.djrill.DjrillBackendHTTPError -- retained as equivalent for backwards compatibility).
* Release notes in readme
* Update example in readme
* Note deprecation of DjrillMessage class
* Longer long_description for PyPI
* Update authors
* Bump version number (setup.py and __init__.py)
* Supports additional Mandrill send-API attributes on any ``EmailMessage``-derived object -- see details in readme
* Removes need for MANDRILL_API_URL in settings (since this is tightly tied to the code)
* Removes ``DjrillMessage`` from the readme (but not the code or tests) -- its functionality is now duplicated or exceeded by standard EmailMessage with additional attributes
* Ensures send(fail_silently=True) works as expected
Test Django 1.2 and 1.3; Python 2.6 and 2.7
Don't bother testing Python 2.5 -- it requires an older version of
requests (that doesn't depend on json).
Don't bother testing Django 1.2 -- it requires changes to ``assertRaises``
in the test cases (because the context-manager version of assertRaises is
part of unittest2, which appears in Django 1.3+ or Python 2.7+).
Don't bother testing Django 1.5 (yet).
Cherry-picked from:
8c26807a - Add runtests.py for testing separately from other Django apps
cd8504b1 - Make tests compatible with setuptools
4ac65b78 - Set up testing on the backend API calls, using mock
