1. Change default ftp site to ftp from ftp12.
2. Remove config -w and -W [Set vnet.interface NIC]
3. Add -f flag to unmount command when releasing memory disc.
4. Change so this version of qjail only runs on 12.0 and newer because pf is vimage aware now.
5. If local install [-f] jump around stable, current check logic.
6. Change/add logic & code to implement bridge/epair method for vnet jails.
7. Change qjail.8 about vimage no longer having to be compiled into kernel 12.0
8. Change "config -v logic to setup vnet jail with pf, ipf, ipf firewall.
9. Add start vnet code to qjail script to check for host/vnet jail firewall mis-match.
10. Add start vnet code to boottime script to check for host/vnet jail firewall mis-match.
11. Update all the manuals to reflect the about changes.
12. Add check to "config" so no ipv4 change for vnet jails.
13. Block config ip address changes for vnet jail because of class c ip allocations.
14. Change verify_ip subroutine to include check for private ip address and 127.x.x.x addresses and put on lo0 interface to make that jail local only.
15. Change verify_ip subroutine to include check for vnet class c address range.
16. Create non-vnet jail using 127.x.x.x ip4 address to make that jail local access only. When config -v to change jail to vnet jail it becomes local access only also.
17. Change "config" -4 & -6 to remove the ip address when the word "none" is used as in -4 none.
18. Change install to check for amd64 & i386 platform architecture and use path with amd62/amd64 and a single architecture path for all other platforms.
19. On "qjail install -f /usr/base.txz" option fixed so it works.
20. Diff options changed between 12.1 and 12.2, Removed the -u.
