Currently, `get_ref()` does not work when `self.digest` is not set as it
assumes that it is a string, which is not the case. This means that
tracking a docker source which does not has any ref set will fail with
a no-so-friendly message saying
`AttributeError: 'NoneType' object has no attribute 'startswith'`.

Fix it so that `get_ref()` returns `None` when the ref is `None`.

Add MAINTAINERS file

Closes #7

See merge request !27

As these files are not supposed to be executed directly, they do not
need execute permissions.

Shebang lines are not necessary for files that are not executables so
remove them.

For more context, plese see
buildstream#424.

move the MAINTAINERS file to the root of the repository.

Currently `docker` source plugin accepts only a single `url` parameter
for the full image path, including the registry endpoint. And later it
splits them assuming that hostname part of the url is the registry
endoint and the rest is the image path. This causes issues when the
endpoint is in fact located at a subpath on that hostname, for example
'http://example.com/my-docker-registry'.

Fix it by explicitly asking for `registry-url` and `image` separately.

As this is a breaking change, bump the version number. Note that the old
format is now unsupported.

Fixes #9.

This should provide some more context of when plugins were added.

Formatting appears to be broken at present as `===` is being treated as
literal.

Fix it and also change other places to follow reStructuredText
guidelines:

- The underline/overline must be at least as long as the title text
- Have a separate adornment style for page title
