Wandering shops

[MunWolf]

So I had this idea running through my head to add the ability/header to randomize the location of npcs
(aka the shops, not sure I would randomize the map lupos or any of the other quest npcs)
as moving the shops away from Glades would shake things up a bit.

But not really sure how that would be supported logically

From a logic perspective, this sounds like a spezialization of door randomization, which doesn't have syntax currently since we haven't implemented any such feature yet
