Libraries are published and consumed from npm

[goldbergyoni]

[This is a copy of Daniel's PR, only the libraries are also published to npm]

• All libs have the same scripts (same interface)
• All libs have "prepare" command to support build before publish
• All libs have prever tag
• All libs have the same tsc config (we should share somehow)
• All libs are published
• No Monorepo to npm link locally (until we decide on the right tool and whether it's the default)
