Rules with "unqualified" license names should count as references, not notices.

This changes a number of rules with unqualified license names (such as "Apache 2.0
License") to be classified as (the weaker) "reference" rather than (the
stronger) notice.

In practice, this means that the `is_license_notice` property is changed to
`is_license_reference` for a number of rules.
