Provide a better set of boot menus when booting via EFI. Previously

had a limited set of hard-coded menu entries - this was buggy and
didn't take into account all the possible boot variations. Now parse
the isolinux menus already provided in the d-i build and generate
equivalent grub menus, complete with themes for a reasonable layout
with graphics and titles.
