connections.cgi: iptables connection tracking.

I finished progress on sorting with connections.cgi and i want to share
with you guys.

Green arrows for sorting on source ip, source port, destination ip and
destination port, protocol, connections status, upload/download and ttl
will now appear on iptables connections tracking WUI.

It would be a pleasure to hear from you guys if you have further
suggestions.


To keep the sorting less time consuming and with a minimum memory
footprint, i added a bash script what is doing all the sorting and removed
the sort command from the piped command line.

The bash script "consort.sh" goes to /usr/local/bin.

The two diffs diff against the "next" git repository:
