Mercantile Screen: Transfers unwanted items

OpenMw: 0.49 dev Deckwind: 4df9170d

Expected Behavior: Transfer item to seller or to player character properly moves only the selected (1) item .

Current Behavior: Transfers the selected item and the one below the cursor, so two (2) items in total. Making it hard to sell/buy items without moving items you might not want to move.

Personal Note:

Thank you beautiful people for making this mod. It's a very promising feature, and I like where this is going. I hope to find and possibly help solve more bugs in the feature. Personally, I have coding experience but not with Lua. If you have any resources which help to learn Lua and OpenMW scripting I would appreciate it.
