trade window subtype

[dutchie1289]

If you want a npc to sell a "vial of oil",
you can only see "vial" in the trade window.
It should state: "vial of oil".

It should be like this:

if item->subtype > 0 {
vial of oil
}
else{
vial
}

It's customary to send a pull request so it can be properly reviewed.

Your commit also includes loads of unrelated formatting changes. They seem good, but should not be mixed up into one change. It would be super nice if you would split it up into multiple commits, so we can discuss each separately (and so future readers know what each change was about).
