pfBlockerNG - Fix Aliastable issue on Nano/Ramdisk Installations
1. On Nano/Ramdisk Installations, the /var/db/aliastables folder gets deleted on reboot. This causes a 60 second delay per alias. This PR archives the /var/db/aliastable/pfB_*.txt files to the pfBNG pbi /etc folder. On reboot the contents of this archive are restored. 2. Remove the previous Fetch Timeout code. 3. Improve the IPv6 Regex code. 4. Minor text improvements 5. Add conf_mount RW/RO to the sh script. 6. Add the aliastables() function to restore the aliastables files on reboot.
