- Packet Transmission is now a separate thread to allow for event processing

Browse Source 
- Packet Transmission rate (IPG) is done - need to test. IBG is still pending
- Per port there are two pcap_t handles - one for Rx and one for Tx: since PCAP does not capture loopback packets, transmission by OST happens on Rx Hdl so that they are recieved on the Tx Hdl
- pcap_loop() changed to pcap_dispatch() to be able to work in PCAP/Linux - forgot exactly why :-)
- Removed NIC stats
- Implemented PortStatsFilterDialog ordering of ports
- PortStatsWindow - Tooltip on Port column dispays stats limitations
