Feature Request: provide easy way to configure background images

Feature Request: provide easy way to configure background images

Grub 1.98 include code in 00_header.in and grub-mkconfig.in to add
theme entries to /boot/grub.cfg, but it does not provide a similar
method for adding background images (wallpapers).

The patch included adds some lines just over GRUB_THEME entriens in
00_header.in to handle the background image.  It will also look for
the image format and insert the module required by it.

I got parts of this patch (code) from somewhere else, but can't remember from.
