2.0RC3, daily builds: Multi-WAN, WAN state detection problem.

[pekmop1024]

There small problem with WAN state detection.
If one of WANs down and state detection ping process recieve "Destination Port Unreachable" or "Destination Net Unreachable", it freezes at "Offline" state even if connection is up after some seconds of down.
I think, pinging continuously some site on the net is wrong method, it must be something like "ping -c10" in cycle.

UPD: now I've added cron job for apinger restart every five minutes, but I hope it's temporary and pfSense maintainers fix this problems.
