Fixes
- Fix Travis so it uses the correct python versions. [7580e6f](https://github.com/jazzband/django-categories/commit/7580e6ff6e447175a37b4b1126df1b5e50665011)
- Fix Travis so it works with Python 3.7. [b9dd8fa](https://github.com/jazzband/django-categories/commit/b9dd8fa80a574f337b1f96f10059f91d4ccd7c89)
- Fix 'Models aren't loaded yet' warning on import. [61e156b](https://github.com/jazzband/django-categories/commit/61e156b3857c3877b1860b05e212409b94f4ace3)
categories.registration._process_registry was being called in
categories/__init__.py, but since Django 1.9 it hasn't been possible to
perform operations with models until the app registry is fully
loaded. Currently the `AppRegistryNotReady` exception is being caught
and printed, which means it is never actually executed on load.
Since this code isn't currently doing anything (other than emitting a
print() of a warning), I've removed it.
- Fix tests. [abec216](https://github.com/jazzband/django-categories/commit/abec2164f2de3759a1898a61b1d10d080201a573)
Also dropped testing Django 1.10 since django-mptt requires Django>=1.11.
- Fix for TOXENV=py27-lint. [d542684](https://github.com/jazzband/django-categories/commit/d542684e3685f86c02937a0df05449eda18ae041)
