ability to specify DNA by URL not path in install
Currently when installing a hApp DNA is specified by path It would be really good if we could specify by URL and have holochain download it.
Actually what we want to do is have holochain accept the bytes of the DNA directly, rather than have holochain fetch it from anywhere. The thing driving Holochain should be responsible for fetching and providing the DNA so that Holochain doesn't have to be concerned with those details.
Created #421 to reflect this, closing this issue
Reopening in light of the fact that browsers may have a hard time corralling billions of bytes over websocket
This is supported when installing a happ or webhapp https://github.com/holochain/holochain/blob/develop/crates/mr_bundle/src/bundle.rs#L141. Closing as done
