add markers for mirage "loot" cache thingies

the zone is already a glitter snow storm, nobody wants to look for purple firefly dust that turns into the loot box... just put them on the map/hud like beasts or abyss dots so we see where they are. so annoying. we shouldnt have to scan scan scan for and look for them when everything in this game is just 10000 trillion glitter atom level fidelity frizzle flying around.
