E2B v1.B8d now available + grub4dos eBook

I hope to release this version as v1.B8 before XMas.

Difference from v1.B7 are:
  • Latest grub4dos 2019-12-20.
  • Improve E2B scripts to allow user to define a greater number of grub4dos environmental variables (grub4dos max is 60).
  • New default background. 
  • Add .vhdx file extension (was removed in last few versions).
  • Update Memtest86 UEFI free version to v8.3.
  • Add Tails_generic_for_USB_HDD.mnu for generic menu for booting Tails ISOs from USB HDD. 
It is in the Alternate Download Area - Latest Beta folder as usual.
