Have LicenseScanner capture licenses from limited information

[nigellh]

Many packages do not have the full license in the package and might just have the name of the license(s).

LicenseScanner should still be able to pick these up.

Sometimes it is just specified in a package definition file such as package.json, but it could just be text at the head of the file.

I will start pasting a range as I come across them.

And yes they were both at the top of a single file!

/** @license URI.js v4.4.1 (c) 2011 Gary Court. License: http://github.com/garycourt/uri-js */

While the license isn't directly specified, LicenseScanner could capture it for further investigation

We should add an example of how to enable by-name and by-ID.
