* Upgrade to Electron 1.8.2 / Node.js 8.2.1
* Update CI Node.js versions
* Make `engines` top-level property
This was accidentally included under `build` which is disallowed
by `electron-builder`.
* Refactor notification updates
Allows easier debugging through variable inspection.
* Use `appId` for Application User Model ID
Recommended in:
https://github.com/electron/electron/issues/10864#issuecomment-346229090
* Update `spectron` to 3.8.0
* Bump `electron-builder` based dependencies
* Use `config.extraMetadata` instead of `em`
Prevents `Unknown argument: em` error.
See: https://github.com/electron-userland/electron-builder/issues/2615
* Revert AUMID to be based on `packageJson.name`
In our build artifact `packageJson.build.appId` causes an NPE.
* Clean logs on startup; install server-side testing/linting
* Add eslint config, make all of app/ conform to its demands
* Add Node.js testing and linting to CI
* Lock project to Node.js 7.9.0, used by Electron 1.7.10
* New eslint error: trailing commas in function argumensts
Node 7.9.0 doesn't like trailing commas, but Electron does
* Move electron to devDependency, tell eslint it's built-in
