#2 Connection to self possible

[Michiel Uitdehaag]

When making a new connection, the default port is the
port the program is listening on itself. If 'localhost'
or 127.0.0.1 is used as remote hostname and the port
not changed, a connection to the own port is created.

This is funny. But useless. And the program is not
prepared for that, as it would need to have twice as
many player interfaces as required (one for the network
stub and one for the local implementation).
