The Observing list tool is now functional. The table view is now a
QTableWidget, and the "Tiny" (name only) view is a QListWidget.What works? Adding objects to the list in the map (popup menu, or "O"
key), selecting them in the tool and using the action buttons. You can
also switch to "Tiny" mode, which shows just the name field and hides
the Log notes editor.TODO: Shrink the window when entering Tiny mode. Sort rows when
clicking a column. ObsListWizard is still a crash.
