Document the ABC

Closes python#36

See merge request python-devs/importlib_resources!40

This change adds `nitpicky=True` (which is an equivalent of `-n`) to
make Sphinx emit warnings for any references to non-existing targets.
Then, it adds `-W` to make it fail whenever a single warning is seen.
Finally, `--keep-going` allows Sphinx to print out all the warnings
before exiting instead of showing just one and bailing.

Resolves python#29
