borg-web 0.5.0

//! The page's messages API over a seeded store, in process (no port): `/api/messages` lists the
//! messages between sessions newest first with whom each was shown to, `/api/drones` gives each local
//! drone its unread count, and the feed shows a send and a refusal. Written through msg.rs's own API.
