The new configuration option "NoIdent" in ngircd.conf can be used to
disable IDENT lookups even when the ngIRCd daemon is compiled with IDENT
lookups enabled.
I changed the test suite to start two test servers (on port 6789 and 6790),
so server-server links can be tested as well for which I included the new
test script "server-link-test.e".
In addition the documentation of the test suite (src/testsuite/README) has
been updated and is more complete now.
