[easytag/wip/win32] Refactor directory renaming

[David King <davidk src gnome org>]

    Refactor directory renaming
    
    Renaming directories broke when porting to use GFile for the current
    path. Fix this by refactoring the functions involved to use
    g_build_filename() and semantically-useful variable names.
