Change model name to `EmbedType`. Update South initial migration. Unicode some strings (one of ours and the result of a newer South.)
Add a `slug` field to the EmbedType model.
Use the forthcoming ArmLayout 1.3.0 and its `TemplatesByTypeMixin`.

The new mixin changes some of the assumptions about template lookup (in favor of being more explicit). So we need to adjust the readme and tests.
We also don't need to test so much of our `TemplatesByEmbedTypeMixin` because it uses an ArmLayout mixin which is already tested.
Tests - move test models into support module like all the rest of Armstrong does.
Fix 2 Embedly tests because the live response is now different...bound to happen when testing real APIs.
Add Python 2.6 support
Remove improper namespacing.
Packaging. Use setuptools.
ArmDev 2.0 support files and dev.txt requirements.
Tests - move to root directory and rename "support" app to simplify.
Tests - use the shared ArmstrongTestCase and provide the `_utils.py` hook as we do in other Armstrong components.
Add TravisCI and Tox configurations
Coverage - exclude import branches, exclude a Django form check, and require South for dev/testing.
Tests - increase coverage. Test the field mixin/descriptor (was missing a TypeError branch) and model slug creation (was missing auto-slug-creation-on-save branch).
Tests - increase coverage. Adding tests for the BackendAdmin, sharing common things, removing the `urls` TestCase attr because that's handled by `ROOT_URLCONF` in `env_settings.py`.
Replace `response_field` with `response_attr`.

"Field" is misleading; this can't be a Django model field. It needs to be an attribute that can handle being deleted. If it was a model field things might look like they worked but I'm sure it'd break confusingly at some point when clearing or refreshing the backend response.
Readme updates.
Requirements - django-extensions and django-model-utils have both dropped Django 1.3 support, but the features we use are unchanged so our package continues to support Django 1.3.

Using Django 1.3 does require using django-model-utils<1.4.
