Syntax	Effect
`on npc click "<name>":`	Runs when a player right-clicks the NPC of that name
`on npc left click "<name>":`	Runs when a player hits it
`on npc click:`	Without a name: runs for every NPC

Inside the block, player is whoever clicked, as in HyperScript's own events. {_npc} is the NPC's number and {_name} its name.
The name is compared without colours and without regard to capitals, so "Guide" finds an NPC called &aGuide. If two NPCs share a name, the block runs for both.
A cooldown line works as on any event, per player.
