Upgrade to Babel 7

See original GitHub issue

That’s not urgent but this should be done at some point. Babel 6 works well and B abel 7 does not have a lot of BC breaks, but it is not possible to upgrade directly, there are a few changes, including:

renaming packages (from babel-xyz to @babel/xyz) in package.json, .babelrc, and webpack config files
adopting babel-preset-env, which is the recommended plugin for a while now. It means we should get rid of the ES2015 preset (deprecated anyway)
