problem: gridftp threshold is being applied to all connections

Browse source 
The bytes_threshold_crossed event in the gridftp analyzer is not first
checking to see if the connection passed the initial criteria.  This
causes the script to add the gridftp-data service to any connection that
crosses a threshold that is the same as or greater than the gridftp
size_threshold.
