New package: IPTraffic 0.8.2

New package: IPTraffic 0.8.2

Please note:
This is a port of the old 'IPTraffics' addon from ipcop to ipfire
done by RadioCarbon (Frank Mainz).
He asked me to publish this for him - ALL programming work was done by him.
I'm only the MITM.

Description:
With the add-on “IPTraffic” you can determine the traffic of a computer
based on its IP address.
Only the traffic between IPFire and the client to be monitored can be determined.
The display is shown once as a tabular overview and additionally a statistical
graphic can be called up for each client over the period of the last hour, day,
week, month and year.
