Stop swimming against the tide and accept what most of the rest of
the world does.
While it adds an annoying depth to the actual source code, it makes
the root directory nicer (no more 'test-res' dirs), means we don't
have to override the gradle config, and makes it nicer to work in
IDEA 2016.1.
This allows it to be used to read other files, such as bundled
defaults.
