Incorrect gold value for common armor and weapon

[Pierre-Sassoulas]

It seems that the WOW API does not give the real vendor value with getItemInfo(). It even gives an item link with wrong value for gold. (64 copper for a 2s99c item).

It's a bug, but I think it's in the WOW API, so I don't know how to fix it right now.

Affect only common weapon/armor, so it only affects the very low level players, because later weapon and armor are grey or green but rarely white.

I don't think I'll take more time for this, but PR welcome :)

Removed it in 0.3.1 because it was annoyingly breaking the feature for grey items.

Maybe reintroduced in 0.6.0 if they are in scrap junk list (?)
