Autoshutdown Plugin - Ping check

@vcdwelt you description of how this work is incorrect:

IP Range: Is just a simple ping check to check if a host is online. It does not require a port to work.

Sockets: This check for connection to the OMV server via ports i.e. is the web OMV GUI open on a system (port 80 or 443) it does not require an IP but will state the client address that is connected.

I tested the script and I think the IP Range check is functional, however there are a a few think to check. Dose the host expect a ping (ICMP packets) respond to them or could this have been disabled? As this is a requirement to get the IP Range to work. Secondly is the scrip running the ping test correctly, you need to check the autoshutdown logs, check both the config was expected (at the start of a script run) and check the output of the IP Range check (its the first check run so it should be easy to see).

If you cannot see anything up post a verbose log (you need to turn this on in the GUI) and send your config. Note: I need just a fragment of the log with the config section and a couple of run of the ip range check. and i see if i can reproduce the problem.
