Litle SDK version 8.27.1

This goes along with the matching branch of the Springboard build repo.

 - Switched to using the libraries module for a definition of the Litle SDK. It now uses that for autoloading the needed files.
 - Added an example make file, like how salesforce_soap does.
 - Added a LitleSDK class to abstract the interactions between the Litle SDK and Commerce Litle.

XmlParser methods coming up.
