    libide/editor: improve save delegate title/subtitle
    
    We want this to be more like the mockups. We use the project directory
    name in the subtitle as the path root just to make things a bit more
    obvious. If it's not in the path of the context, then we use collapsed
    path names starting from HOME. Finally, give URIs something special so
    that it's more obvious where it comes from (ssh://host/ for example).
