Consider deprecating module_from_template

[Archmonger]

While the ability to load JavaScript modules from NPM on the fly is clever, it technologically isn't possible to do properly.

That is due to ReactJS version mismatches, which frequently pop up when using this API.

For the health of this framework, I would recommend we deprecate module_from_template and double-down on JavaScript Components API docs to supplement this.

I think I agree. An idom-build cli will also help with this.
