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
In your experience, does it make sense to make this a config item?
