Bug#789798: Updated patch to "add option to _not_ install to UEFI boot order"
Attached new patch inverts the sense of the option after review of the
wording by debian-l10n-english and fixes the propagation of the setting
to the installed grub2 package.
Ian.

Subject: [PATCH] Allow avoiding installation to NVRAM on EFI or IEEE1275
systems
On systems which demand greater control over the boot order (e.g. ones which
PXE boot) it is useful to avoid messing with this during installation.
