A few more improvements to make network debugging easier.
The port checking facility now tests for two different scenarios:
1) EchoHam connecting to another station (Outgoing Connection)
2) Another station connecting to EchoHam (Incoming connection)
Most modern routers will support outgoing connections without any special requirements.
Incoming connection pose more of a challenge and need port forwarding to be functioning correctly.
As of V2.13 the Port Check user alert will report separately on Incoming and Outgoing connections to enable better network diagnostics.
