Update libraries

Target Browser Support

Minimum supported versions (based on ES6+, IntersectionObserver, CSS Grid support):

• Chrome 64+ (January 2018)
• Firefox 63+ (October 2018)
• Safari 12+ (September 2018)
• Edge 79+ (January 2020, Chromium-based)

This allows removal of ES6 polyfills (core-js, regenerator-runtime) and use of modern APIs.

We should definitely include all those dependencies in the package.json so they are easy to manage. I can do it, but I am waiting for @chris-steele to open his new PR.

jQuery, only used for one thing? I can remove it from where it is used. Okay, it is used everywhere. The AJAX stuff can be done with js native fetch or axios.
jQuery UI, how much is it used? I will review.
Handlebars, I believe, are discontinued. There is a new lib, forgot its name.
Moments, see what alternatives there are. Day.js?
selectize.js, use tom-select
Babel, do we really need it these days?
That colourpicker one, spectrum, replace it with the native HTML color picker input.
scroll.to, pretty sure it easily can be done with js
velocity, I think GSAP is used these days, but it is not an 1:1 replacement. Maybe we can get away with css animations?
backbone, maybe use React or something? Clearly this is nothing one can hand-weave.
