Environment
The following can be modified on a per-instance basis by setting the environment:
SECRET_KEY - Should be unique (required)
WORK_DIR - Where to store DB, index and cached files (defaults to BASE_DIR/data)
DEBUG - enable debug output
Settings files
These all derive from polyphonic.config.settings.base
base - some sensible defaults.
dev - enables logging and the debug toolbar
docker - adds the WhiteNoise module. Should remove this as docker packing adds a custom settings file.
