:: chat-cli: cli chat client using chat-store and friends
::
:: pulls all known messages into a single stream.
:: type ;help for usage instructions.
::
:: note that while the chat-store only cares about paths,
:: we mostly deal with [ship path] (aka target) here.
:: when sending messages (through the chat hook),
:: we concat the ship onto the head of the path,
:: and trust it to take care of the rest.
