[PATCH] make default and once boot entries independent

[P]

There is a problem with the "savedefault --once" functionality
(at least as comes with redhat's grub). The default entry
and "once only entry" are not independent, and so after
a "once only boot" the default entry will be reset to 0.
I can't see how that would ever be required (especially
if the "once only entry" is also 0).

I've modified the patch to make these independent so you
don't loose your previous default entry.
