#10 Functional AMP interface

[Ted Williams]

Currently AMP calls to the engine require that the agents receive an AMP message structure and return and AMP message structure as defined in the Agent Message Protocol documentation in the Ais project.  Add a new interface that strips the names from the incoming name-value pairs and passes the arguments to the function in the same order as in the incoming AMP message.  Convert returned values into a string and return back packaged as an AMP message.  Only the ReturnType 0 (AMP) is supported.
