Allan Jude f1aba489c1 Introduce the ZFS Boot Environments menu to the loader menu
If the system was booted with ZFS, a new menu item (#7) appears
It contains an autogenerated list of ZFS Boot Environments

This allows the user to switch to an alternate root file system
Use Cases:
 - Revert a failed upgrade
 - Concurrently run different versions of FreeBSD with common home directory
 - Easier integration with the sysadmin/beadm utility
