 Subject:  Magic Shaper and Bit Torrent

There is a rule needed that Magic Shaper does not currently create for 
Bit Torrent to be shaped properly in the downloading (incoming) 
direction. Some BT clients connect from any port to ports 6881-6999 on 
the local computer to send data. Therefore a rule such as WAN incoming, 
TCP, source any, dest 6881-6999, Queue 7 (as Magic Shaper is currently 
configured - whatever the hated download queue is).

Without this rule only connections where the local machine has 
initiated the connection will get shaped, but the BT protocol allows 
for either machine to initiate the connection.

Probably a similar rule is also needed for BT uploads, but I have not 
tested this yet.
