Replace type: "bare" with type: "server" in attributes.json. This now just
means "only make one server process" rather than controlling the boot script.
Programs that are type: "traditional" that want to be a webapp now need to
explicitly depend on the webapp package.
remove unused websocket (if we need it again outside of the streams package
we'll probably be wrapping it in another npm module anyway)
shrink dev bundle version number location to just one place!
