Gfxboot theme for booting

[Juanje Ojeda Croissier <jojeda@emergya.es>]

Hi guys! :-)

My name is Juanje Ojeda and I'm working on Spanish distribution called 
Guadalinex. The distribution is actually based on Ubuntu, but we prefer to use 
Live-helper than the Ubuntu generation system, so we are making some 
improvements to support things we need.

The other day my coworker Roberto sent a patch for one bug (#515974) that was 
blocking us. But we're still working on couple of things.

We hope you find some of those useful and if you prefer any way we give to you 
our patches or features, just let us know.

Well, the last feature we needed and Roberto has implemented (trying to doing 
similar to the rest of the code and being as less intrusive we could) was a 
gfxboot support.

We need graphical splash and menu, because it's what our users are expecting.

Roberto added some variables and a new 'stage' that will run after 'syslinux' 
stage (which is kind of predepend for gfxboot). The files needed to enable the 
graphical boot will be extracted from a theme already installed in the 
generation system.

Actually you can put the files on:
/usr/share/gfxboot-theme-${LH_GFXBOOT_THEME}

or

/usr/share/gfxboot-theme-${LH_DISTRIBUTION}

and it'll work.

We hope you like it and if you have any though, advise or comment we love to 
read it :-)

I attach the patch file.

Thanks for your time :-)
