Inform players about trading

[OrionFive]

Use a first time only popup(quest notification?) that tells players when a trade has been struck, giving them a little of that information and giving them a form of feedback when they've successfully sold something. (This was my major stumble, I was growing my silver reserves too fast on my my own and selling from a bulk stockpile to actually notice if trades were happening.)

"A pawn from another tribe has purchased one of your items for silver! Increasing your reputation with their tribe will encourage them to bring more silver to spend on visits, allowing them to purchase more expensive wares.

In general, they'll prefer undamaged, high quality items around their own tech level, though basic materials can be bought by them too."
