Editing WoW:API GetTradePlayerItemLink (section)

==Details==
<!-- Details not appropriate for the main description can go here -->

: Remember, chatItemLink(s) are different than itemLink parameters needed by many APIs.  To properly extract an itemLink from a chatItemLink, here is a neat function:
 --[[ Function: extractItemLinkFromChatItemLink
      Purpose: gets an item link string from a chat item link string
      Note: don't ask questions, it works
   ]]
 function extractItemLinkFromChatItemLink(message)
   local _, _, _, _itemLink = string.find(message, "(|H(.+)|h)");
   _, _, _itemLink = string.find(_itemLink, "(.-|h)");
   return _itemLink;
 end

: Here is a chatItemLink Example:

 |cffffffff|Hitem:3771:0:0:0|h[Wild Hog Shank]|h|r

: Here is an itemLink Example:

 item:3771:0:0:0
