Remove dependence on jQuery

[jacobq]

Is your feature request related to a problem? Please describe.
Since ember, materialize, and velocity do not require jQuery any more, it'd be nice to be able to drop it as a dependency to achieve a smaller payload & simpler codebase.

Describe the solution you'd like
It looks like jQuery is still used in quite a few places, but most have simple, native alternatives. I would like for those be refactored. For example this part of md-tabs.js can be rewritten as

import * as velocity from 'velocity-animate';
// ...
if (!animate) {
  const el = this.element.querySelector('.indicator');
  for (let [key, value] of Object.entries(cssParams)) {
    el.style[key] = value;
  }
} else {
  velocity(this.element.querySelector('.indicator1'), cssParams, {
    duration: 150
  });
  velocity(this.element.querySelector('.indicator2'), cssParams, {
    duration: 150,
    delay: 40
  });
}

Describe alternatives you've considered
The alternative to taking jQuery out is leaving it in, which is what we already have. I suppose an alternative to replacing it with native API calls would be to use another library, but I think that would be missing the point.
