adding gummi_entries module

this module needs the bootloader module enabled, grub disabled
gummiboot automatically adds entries for UEFI Windows systems and any other OS already using gummiboot
conf files.  This module adds a gummiboot .conf for a grub based UEFI OS.
At this point, only the first entry found is added.
Module is tested on real hardware, multiple systems & installs
What do you mean by that? As I see it, it just updates grub.cfg you created with bootloader module. It seems to be a workaround to get gummiboot working.
