Bug#500134: /etc/grub.d/05_debian_theme: make changing splash image easier

[Krzysztof Burghardt]

Package: grub-pc
Version: 1.96+20080724-10
Severity: wishlist
Tags: patch

Dear GRUB2 package maintainers,

I'd like to introduce to /etc/grub.d/05_debian_theme config file enchances
provided by Yan Morin. Those enchances makes changing colors and splasimages
easier. If you, decide to accept this patch I will provide grub2-spalshimges
package with updated README to keep it in sync with grub-pc package.
