modified the double-click handling in the DBTreeListBox
various stack trace reports suggest there are scenarios where a double click
handler somehow destroys/corrupts the list box and/or its entries, but the
subsequent default handling in the SvListBox class accesses those corrupted
entities.
Since we're not able to reproduce any of those crashs, the handling in the
DBTreeListBox and its clients now is as follows:
If a double click is handled, then the DBTreeListBox::DoubleClickHdl will
return 0, this way causing the SvListBox to *not* process the double
click event further.
