Pawn arrow support please

[strickland]

I am using the latest version and still the arrow for items which are upgrades are not showing in the item itself, it only shows within the tooltip, I am not sure if someone else created an issue for this, but it has been a very long issue.

There are a pull request avalibale to fix this. #504
Why it is not accepted/merged yet is a mystery though...

See #503.
