tcpick 0.1.24 released

Changes: An option `-Enum' to exit when `num' connections are marked as CLOSED that differs from `-Efnum' that exits when all the first `num' tracked connections are marked as CLOSED. An option `-Tfnum' to stop tracking new connections when `num' is reached. Added a balanced AVL tree to the ip lookup engine. Works successfully under OpenBSD and NetBSD. Several bugfixes.
