NPM and the License List

The site now:

1. Displays links to license texts on spdx.org, including for dual-license and other non-trivial SPDX expressions
2. Displays a tiny green OSI logo (and obligatory registered-trademark symbol) for packages that offer at least one OSI-approved choice
3. Displays license information only for packages in the registry that set `license` in `package.json` to a valid SPDX expression

To see it in action:

The NPM project uses the License List short identifier to describe the licensing of a Package.
