Added extra metadata options to publish and package commands

Browse source 
You can now run these commands like so:

    datasette now publish mydb.db \
        --title="My Title" \
        --source="Source" \
        --source_url="http://www.example.com/" \
        --license="CC0" \
        --license_url="https://creativecommons.org/publicdomain/zero/1.0/"

This will write those values into the metadata.json that is packaged with the
app. If you also pass --metadata= that file will be updated with the extra
values before being written into the Docker image.

Closes #92
