* Upgrade to jQuery 3.2.1
The jquery-migrate showed a number of warnings,
but no errors, so it should be safe to use.
Warnings mostly related to bind, unbind, focus, ...
https://github.com/jquery/jquery-migrate/blob/master/warnings.md
To enable jquery-migrate, I added it to package.json, and added
a require('jquery-migrate') to the webpackShims/jquery.js right
after the require('jquery').
