Remove PM Trade messages, add notification to Trade button

I find it pretty annoying to get hundreds of messages per week about people wanting to trade with me. I would love to look at all of the trades, so turning it off isn’t an option for me. There are notifications for messages, friend requests, and now that we have the new site layout, it’s possible for the trade button too.

The button might have to be changed to ‘Trades’ to make it similar to the other items with notifications.
