Revise the scope precedence in the MPI_Publish, Unpublish, and Lookup functions. If a global server was specified and is available, then default to using it for all three functions. If not, then default to using local scope. If an info_key was provided, then it takes preference. We always follow the user's direction - this change only impacts the scope ordering if the user -doesn't- tell us the order to use. This commit was SVN r19146.
