Issue with install.sh while setting fully qualified hostname option

While installation I encountered a bug with the http://software.virtualmin.com/gpl/scripts/install.sh with "-host" option as in the following:

sh install.sh -host example.com

I looked into the script and there is a small miss match with the hostname options as follows:

Line# 65: Help text.

echo "  --hostname|-host: Set fully qualified hostname"

Line# 75: The option.

--hostname|--host)

There is an extra "-" on line# 75.

Please refer to the attached screenshot for reference.

Also, I can help with the patch file if you want me to do it.

Great script guys!

Cheers!
