add trigger definition to a triggers tab on object definition box
Currently, when hovering over table objects, and clicking on the table name mini popup, you get the object definition box, with a 'Script' and 'Summary' tab.
The 'Script' tab has the table and index creation scripts, and the 'Summary' tab lists the column definitions.
For tables with triggers, it would be nice to have a 'Triggers' tab that contains
any trigger scripts for the table.
