Suggestion #1685

Create another type of Sell sign that gives people the ability to trade out items with the click of a sign, for instance - the sign would read somthing like this..

[trade]
item wanted
item available for trade
(Cool down timer) <- Keeps one person from cleaning it out.

With the addition of Banknotes it could be a new way to sell items for Banknotes, while also limiting them from buying the whole shop out, due to the timer.
It could also be helpful if someone is wanting to trade eggs or Kits while offline.
