Example deployment scripts

Adds `npm run bundle-pack` for creating a deployment archive and `npm run deploy --to=...` for deploying that archive to a remote server.

I've got some rebasing and commit cleanup to do, but I think this is otherwise ready for more eyes.

There are `README.md` updates too, so @crandmck and/or @chandadharap might want to weigh in on those.
