    shellDBus: Add ListExtensions() and GetExtensionInfo()
    
    GetExtensionInfo() takes a UUID and returns a JSON object with information
    about that extension including their metadata, path and current state.
    
    ListExtensions() takes no arguments and returns a JSON object mapping UUIDs
    to the same information objects described above.
