Filter by tcp-port is in Readme, but not in default configuration

[indeyets]

Readme says:

If a numeric is used as the keyword, it is matched to PID, TCP, UDP by default

But in reality, this filtering doesn't work by default and user has to create config-file and add TcpPort, UdpPort columns to it.

I'm not sure what would be the best solution here. It can be rewording of Readme which leads user to custom config or it can be tweaking of implicit (default) configuration
