The following patch allows for the addition of arguments through a
system file. The patch looks for a file named "openconnect.ini" in the
"/etc/nm-openconnect/" directory. If the file exists, it reads its
contents and searches for a line that starts with "ARGS=". If such a
line is found, it extracts the arguments and adds them to the
/usr/sbin/openconnect that is spawn during connecting.
This patch probably needs need some tlc.
