[PATCH] Display binary prefix filesizes instead of decimal prefix filesizes (344296)

[Raphael Bosshard <bosshrap zhwin ch>]

See http://bugzilla.gnome.org/show_bug.cgi?id=344296

This patch changes the human readable filesizes 
(gnome_vfs_format_file_size_for_display) which are curently displayed 
(rather missleading) with binary prefix multipliers (such as Kilo, Mega, 
Giga) to more appropriate binary prefix multipiers (Kibi, Mebi, Gibi). 
The IEC approved standard symbols (KiB, MiB, GiB) are used.

For more information please read http://en.wikipedia.org/wiki/Binary_prefix

So long,
Raphael
