[Mod Request] Placeable Spawner (for dungeon building)

[tg08096]

I don't think I need to flesh out this idea but just the vanilla spawners are a great start. Another great feature would be a two-part spawner where an activator could be placed, for example, outside a room or down the hall and when activated would spawn the mob without the player knowing the creature hadn't been there the whole time.

 

The only activator I have seen so far on the nexus is PressurePlate for Doors
