ShowItem 1.5.13 - More API and custom model icon support
Add API methods to show items and inventory similarly to how the commands do it. See the Javadocs for all available methods. Let me know if more are needed
Added ability to define custom model data for mapping icons to show in chat. They are defined by using <itemtype>:custommodel:<modelinteger> as an entry in the normal map list (see library code)
Added some missing IDs to the flattening iconrp mapping
