* Django 1.8 requires TEMPLATES setting (for admin tests)
* Ignore cycle tag deprecation warnings
One remaining PendingDeprecationWarning: "the imp module is
deprecated in favour of importlib" is coming from six, and has a fix
waiting to land: https://bitbucket.org/gutworth/six/issue/112
Closes#82.
* Test mock API responses (with actual content) in admin tests.
(This exposes failure case, at least under Python 3.4/Django 1.6.)
* Parse json from Response.text, rather than raw Response.content
bytes, in admin views.
