[gnome-builder] project-tree: implement copy and move

    project-tree: implement copy and move
    
    This allows dragging contents within the tree as well as from
    external programs that support text/uri-list (such as Nautilus).
    
    We rely on the change monitors to rebuild nodes instead of
    manually removing nodes from the tree when doing moves. It has
    the chance of breaking if the user has run out of inotify
    watches, but that's not something I really want to deal with
    protecting against here (instead we should get the sysctl bumped
    or something to that nature).
