merge InteractBase into Interact

[piever]

This merges InteractBase back into Interact. I've removed the Manifest.toml from the docs because it was still trying to install InteractBase, not sure why.

Note: the build step downloads files from https://github.com/piever/InteractResources. Some are standard js, css things, and there are a couple of custom made css from bulma (to adjust styling of rangeslider and confine css in jupyter notebook), that are compiled using this scss https://github.com/piever/InteractBulma.jl/tree/master/assets and this package https://github.com/piever/Sass.jl.

I imagine InteractBulma (useful to add more Bulma styles) can be moved to JuliaGizmos, and we may consider a more standard way of distributing those files.

TYSM!

I'll check this out later. :^)

Ultimately I just want to update this in tandem with WebIO/next. I have some thoughts on a simpler asset pipeline as well (using GitHub assets). Ideally we'd use Artifacts.toml but I'm not sure how well that would work with the kinds of assets we'd be downloading. 🤷‍♀️

Should we go ahead with this? I'm realizing that I will not have much time to devote to Interact development in the foreseeable future, so for me it would make a lot of sense to merge the repo in my own github account (that is, piever/InteractBase.jl) here.

I guess that removes one extra hoop to new contributors (they don't have to figure out that the code lives somewhere else).

I'll leave it up to you. I'm also not having much time these days.

Just a comment: If you're doing this (which would certainly be nice), consider bumping the deps, to the latest versions ... 😉
Particularly, Knockout (0.2.4) and Observables (0.4)
