    file-operations: Use a GList** for the to_delete output parameter
    
    The to_delete GList* gets initialized in trash_files() and is supposed
    to be filled by trash_file() so that we know which files we want to
    delete directly when the call to g_file_trash() fails for some reason.
    
    However, this GList* gets modified in place by calls to g_list_prepend()
    and so those changes will only be seen by the to_delete argument inside
    trash_file(), but not by the local variable defined in trash_files(), which
    will continue to point to NULL regardless of those changes.
    
    So, we simply need to pass a reference to the GList* so that any change done
    to the structure of the GList* inside trash_file() is seen in trash_files().
