[PATCH] Modules compression for grub-mkrescue

[Szymon Janc]

Hi,

Following patch allow grub-mkrescue to compress modules. It also uses xorisso 
option to reduce image size as proposed in 
http://lists.gnu.org/archive/html/grub-devel/2010-05/msg00100.html

It supports both xz and gzip compression. Yet, xz is disabled in this version 
as it generates some issues: wrong symbols in fshelp module (I'm not sure if 
this is a bug in xzio or not).

Generated image size:
no diet         1966080 B
diet with gzip  1048576 B
diet with xz    983040 B

Should be usefull for floppies.

Comments are welcome (I'm not very good at shell scripting :)
