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

[David King <davidk src gnome org>]

commit 1fe7860e7f7097f4c0fe8381076db2245c4ecc05
Author: David King <amigadave amigadave com>
Date:   Mon Feb 3 21:37:20 2014 +0000

    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.
