BLUEGENE - Minor format change for printing out conn_type
BLUEGENE - default geo make 0 instead of NO_VAL.  This is the first thing
that happens when it gets to the controller anyway.
BLUEGENE - Don't ignore a conn-type request from the user.
Handle better if geo is 0
BGQ - Force a request on a Q for a MESH to be a TORUS in a dimension that
can only be a TORUS (1).
