Let wandering traders join villages

Last time I checked, this doesn't happen, but my suggestions suggests if a wandering trader walks by a village, they will "check it out" (possibly by "gossiping" with the villagers of that village), and if they like the village (which may be determined by random) they will become a villager of the village. I think this would be a nice, small little add on.

  when i first played the new update and saw one of these guys, I was hoping they would become a villager after a while. But they didn't, which is upsetting.
