Subject: From: Rob Smart <SMARTROB@uk.ibm.com>

This patch allows an object to directly message another object given its
key using the method osMessageObject(key objectUUID,string message).

to communicate with an object it must implement the dataserver listener
method. The dataserver method is passed the key of the calling object
and a string message.
