* Update deps except eslint
* Update eslint and lint:fix (WIP, needs manual fixing for remaining 44 problems)
* Manually fix remaining eslint errors
* Document deprecation of `version-string` as of electron-packager 9.0.0
* Upgrade to Electron 1.7.9 (chrome-58, node-7.9.0, v8-5.8)
* npm: Disable generation of package-lock.json and gitignore it
--Trying this, package-lock is a pain in PRs. May not be a good idea
(obviously we lose deps pinning), will revert if necessary.--
* npm tasks: add dev-up-win for Windows developers,
and e2e for end-to-end tests. Update docs.
* Move normalizeUrl test to a jest unit test, makes no sense to be in the mocha e2e tests
* Switch from babel-preset-es2015 to babel-preset-env,
with target.node=4.0. Seem like it's today's most convenient
way to support the latest ES and let babel transpile to what
makes sense for our currently minimal node version
