[Project Manager Menu] Add FixInsight to the module node menu

In order to run FixInsight for a specific unit a have to make this unit the active unit, have to call FixInsight from the popupmenu for the project node and have to choose "Analyze current unit only" from the dropdown menu of the "Run" button. That is a bit cumbersome. The module nodes should have a FixInsight menu item that shows the FixInsight settings dialog with a "Run for current unit" button.
