This patch desactivates the following annoying behaviour :
When the eggdrop can't link to another eggdrop (example : the eggdrop's machine is down), it automatically tries some other adjacent ports.

This patch makes this behaviour a compile option, and deactivates it by default.

It has been made against eggdrop 1.6.10, but should work on older versions too, since this code seems old.
