    project: add IdeProject::file-renamed
    
    This is a convenience signal for widgets like treeview to connect to so
    that they can shuffle project files around. As long as plugins use
    ide_project_rename_file_async(), other plugins can receive this signal.
    
    This also fixes a bug where we weren't creating intermediate directories
    before moving the file.
