Enhancement: Add hping support

TCPPing did slow down the frontend alot. Also it is very depricated:

"When I wrote this script in 2002 I was not aware of better ways to measure TCP round trip times. Right now I use hping2.."

I found a HPing smokeping module at https://lists.oetiker.ch/pipermail/smokeping-users/2012-November/004995.html

This works fine and is much faster. HPing3 needs root rights to run. http://comments.gmane.org/gmane.network.smokeping.user/4153

Only option I found is to let hping3 run with sudo and NOPASSWD
