change behavior of single-click in querybean results table
The querybean results table currently listens for list selection events, and
when a record is selected, the document is downloaded and opened in a window.
Need to change this behavior so that single clicks only select a record, and a
double click would download and display a metadata document. This allows other
actions (like "edit") to be associated with the querybean resultset records, for
example using a popup menu (right click on PC, click and hold on Macs).
