[easytag/wip/application-window: 22/22] Use g_format_size() instead of custom code

[David King <davidk src gnome org>]

commit d060fa9b965e89e68f61dc565168b115f826624a
Author: David King <amigadave amigadave com>

    Use g_format_size() instead of custom code
    
    Replace Convert_Size() and Convert_Size_1() with g_format_size() to
    avoid potential invalid memory accesses.
