TCPlot modifications

The module has been modified so that on shutdown, it prints out tables for each client and server. These tables detail how many packets the sources sent of any given size, in decreasing order. It also indicates what percentage of the packets from that source were of that data size.

I added this thinking that it would be somewhat useful as an analysis tool, but also that it would be useful for refining the graphs generated by the module.

So I added two arguments to the module, which will cause it to ignore packets of sizes given in a list for each the server, and the client. It's easier to show than explain. You can run `chopshop .... "tcplot -s 48,52 -r 85,38,103"`, and the module will ignore all packets of sizes 48 and 52 when sent by the client (the `s` argument) and will ignore all packets of sizes 85, 38, and 103 when sent by the server (the `r` argument.)
