Missing defaults for PipeConnection::flow_direction / connection_type

[BrainGamer_]

In 1.1 PipeConnection::type had a default of "input-output" and apparently the renamed field in 2.0 still does aswell but its not mentioned.
The new PipeConnection::connection_type property apparently also has a not mentioned default value of "normal".

Thanks, I noted some defaults on PipeConnectionDefinition for the next release.
