Fixed Dinosaurs bug where feeds with articles with no dates were ranked using the wrong date - they now use the date the article arrived
Made the Dinosaurs months field ignore any character that isn't 0-9
Fixed a performance issue with the Current Activity window
Stopped removing long-running activities from the Activity Log and Current Activity windows - some activities do run for hours. (Unfortunately. iCloud, of course.)
Fixed bug where feed icons didn't always appear promptly in the sidebar
