'Secure Erasure': Now a prompt informs about the need to reboot system after erasing the disk, which also takes place automatically when done
'chroot_conf' > 'Custom System Configuration': Now when 'grub' is selected, enabling services will take effect only if a(ny) service(s) have been first set to be enabled
'chroot_conf': Renamed a few 'HERE-docs' for clarification
'Select Desktop' > 'Custom System' > 'Custom Packages Setup': Now, if 'lightdm' has been set as a custom package, a prompt will ask you to select between 'lightdm-gtk-greeter' & 'lightdm-slick-greeter' for convenience, and said greeter will be automatically installed and also lightdm automatically configured for said greeter.
NOTE: The user only has to set 'lightdm' service to be enabled in next step
