Subject: [PATCH] do not add default listening port if ssl ports were specified

Cosmo Kastemaa reported that its impossible to create an ssl-only setup,
as ngircd binds to port 6667 by default, even if setting "Ports =".

Only add the default port if _both_ "Ports" and "SSLPorts" are
unspecified.

Fixes bugzilla #98.
