Support Node.js 10

[lights0123]

As mentioned in sindresorhus/electron-store#103, this package can support earlier Node.js versions. Version 8 failed in a Docker container, but 10 didn't, so that's what I went with.

Also included lodash as a dev dependency, as I presume that you had it installed globally on your machine.

If you're interested, here's the output of the failed test on Node.js 8:

v10 and v10.10 didn't pass the test suite in my system, but v10.12 did, I went with that. Available in v1.3.2 👍
