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.

This looks at the library definition and loads all of the files in the library. Its return value is the number of files loaded.
