* Also let the dot in py.test die so that upstream is happy again :)
* Update tox to 2.9.1
* Make sure that our urlconf is reset *after* we set MEDIA_ROOT
* Adapt file extraction handling to new TMP_PATH prefixes
* Less dump_apps hacks since the apps.json file isn't present at the
beginning of any test now thanks to temporary paths for every separate
test
* Rewrite read-only-mode tests to cope with pytest settings fixture
* Remove atexit hack from settings_test
This will probably make things a lot easier for ui-tests as well.
