* Add a few script aliases.
* Be more explicit with the lib files included.
* Switch to the caret operator for deps and update them.
We have a package-lock.json file to ensure the deps are what we want.
* Travis CI: add Node.js 10.x.
* Move eslint mocha where it's needed.
* Update devDependencies.

* eslint 5.x doesn't support node.js 4.x, so don't update it
* Refactor package.json properties.
* Update Travis config.
* test node.js node 8 and remove 5 and 4.0
* cache the node_modules folder
* switch to double quotes
