[GM Command] #list npcs Goto option now goes to higher Z if selected NPC is a boat. (#1349)

* #list npcs Goto option now goes to higher Z if npc selected is a boat.

Makes using #list npcs and using the goto button more useful when NPC is a boat, as normal Z will put you in the water.

* Use ?: instead of bool multiply

* Update command.cpp

zone/command.cpp
