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.

I ran into the problem where I wasn't using an ini file with settings, and the SDK requires these settings, so now we're passing them in here instead of with an ini file.
