Debug log updates, error message updates on curl failure

Config setup works with null data if no data is set.

Debugger is now launched in the AamzonIncentive class at the beginning
Debugger id/debug flag set is now one static call
Debugger methods all have proper PHPdoc documentationn added

Fixed Client/Curl error messages to include the original error message
too. Also made sure that a possible null endpoint is not throwing errors
