Flexible TLS port filtering

[JaimeGomezGarciaSan]

TLS port filtering is hardcoded in bpf.py in the following code:
if (dport == 443 || sport == 443 || // port 443 for TLS
dport == 990 || sport == 990 || // port 990 for FTPS
dport == 3389 || sport == 3389 || // port 3389 (RDP TLS)
dport == 8080 || sport == 8080 || // port 8080 for TLS
dport == 8443 || sport == 8443) // port 8443 for TLS

I prefer that the ports to be filtered can be specified in a config file or in command line. This looks too static to me.
