LibItem

I have spent considerable time debuging the War Lookup tables and hidden API
functions to grab stats in a dynamic matter that doesn't require addon specific
lookup tables. This is an attempt to centralize all of the Item lookup and
helper functions for getting stats on Items.

Currently:
    * ItemLib.Get*(W)String(itemData) functions that will take an item and
      return a (w)string for requested * value, such as Name, Rating, and most
      other stats. It will return a table of strings for types that can be on
      an item twice, such as bonuses.
    * Dynamic lookup of Potion stats! Give the itemData and get a table of
      correct stat descriptions and for all the use: strings. This is bundeled
      with the same GetBonuses call.
    * All strings return will be part of the WAR function returns, so return
      strings will be in the same localization as WAR.
    * Versioned with Libstub, this library is embeddable and can also be loaded
      as another addon, developers choice.
      
Current TODO List:
    * Use libstub
    * Fix function logic so I dont do WStringToString and then call the GetStr
      from GetWStr.  I found this late and wanted to quickly fix the wrong
      behavior.
    * Add a generic GetStringItem( itemData ) method that will do just a raw
      print of all the other calls on an item.
    * Add a GetStringifiedItemTable( itemData ) that will return a table that
      is itemData equiv except instead of reference ids it will have text
      strings
    * Support more information, such as talisman data on item
    * Add Has* methods.
