Items from vendors that can't be afforded should have a darker icon

[AdunSaveMe]

If a player doesn't have enough resources or currency to afford an item then that item's icon should be darker to separate them from the rest. I believe it would save a very significant amount of time in browsing vendor menus, especially ones where players frequently make several purchases at a time such as the Entrati members with their trade-in tokens. There's way too much hovering required in this interface already; this would cut down on it.
