Fix inconsistencies in guest nick name generation When the setting net/nick is empty, HW generates a guest name. But there were several problems: - Team name did not match guest name - Random guest number was re-rolled multiple times, causing inconsistencies - Guest number was often too large (now capped at 99999)
