Some dep updates

* Migrate to newer SPDX v2.x syntax in `package.json`

See also:
* [https://docs.npmjs.com/files/package.json#license](https://docs.npmjs.com/files/package.json#license) ... note deprecation of plural form
* [SPDX license expressions](http://wiki.spdx.org/view/LicenseExpressionFAQ)
* [SPDX license expressions Examples](http://wiki.spdx.org/view/FileNoticeExamples)

Note(s):
* Interesting that the newer specification doesn't seem to exist for custom MIT licensing terms which are part of that specification and a few other license types including GPL required Copyright information e.g. not fixed format with the `url` property seeming to be missing for pointing to the LICENSE content. Refer to local raw LICENSE.* files for exact text including `and later` revisions of GPL if ever encountered. In other words SPDX doesn't seem to account for this if a change comes through the pipe but LICENSE.* will always supersede.
