Change the default for auto-destruction of leases.

Before it defaulted to no auto-destroy and you specified -A to turn it on.
Now we default to auto-destroy and you specify -N to turn it off.

I was being overly paranoid and you can accomplish the same thing by setting
the autodestroy sitevar for each lease type to 0.
