Use Vega and Vega-Lite from jsdelivr

[domoritz]

This will make it easier to switch versions in the future.

@domoritz When the jsdelivr links are used, how are they imported? JS usually created one global variable to access all the library fucntions but it can't be accessed somehow. One method can be to import it in componentWillMount but that will be highly redundant and inefficient.

I think we should do this in webpack somehow or with lazy imports (maybe later).

Loading vega and vega-lite from cdn?

[domoritz]

Yes, in production only, though (or have a somehow the npm version as default so VL and VG devs can use the editor)!

This would be helpful when troubleshooting from altair as well. Now there can be a difference between the version used by altair to render the spec and the version used when clicking "show in vega editor", which can make it confusing to troubleshoot. Example here related to vega/vega-lite#9078:
