ConversationTrait
constConversationTrait:Trait<{choices: () =>ConversationChoice[];ends:boolean;entered:number;line:string;node:string;npc:string;speaker:string;title:string; }>
The conversation a player holds with one NPC, on her character: what the panel shows, with its values filled in and its hidden choices left out. A player holds one at a time. The conversation system writes it each node, and a room streams it to her alone, as it does her bag.
