Anti Trade Scam

1 feature addon:
Displays an overlay covering the trade window whenever you are traded/trading someone outside of your raid party. In order to make the overlay disappear you have to type "YES" in an input field.
Purpose: Avoid getting scammed by people staying around enchanters that are opening trade windows with people that are coming to get enchanted.

Looking to implement another feature: displaying the same overlay when someone changes what they put in the trade window fast before accepting.
