Moved enable/disable download buttons code to a generic method.

Changed code to enable/disable Download buttons on Reports tab in Utilization explorer. Buttons were not getting enabled/disabled based upon result data when user sent up tree_select transaction while user was on Reports tab. Existing code was only handling enable/disable of download buttons when switching tabs.
