Fixed sorting to permanently keep "All Sources" at top.
Fixed "Updated" column to sort correctly instead of lexicographically
Added option to show individual count of unread items for each source.
Modified date-calculating code to be more compatible with older versions of MacOS 8.
Fixed fetching of sites such as VersionTracker which would timeout and never show information. If the timeout happens, it tries to use whatever data has come in up to that point and notifies you with a "Note:" message.
Changed timer behavior to reset itself if a manual fetch is done. So, if you set the timer to refetch every 2 hours and you do a manual fetch 1 1/2 hours later, the next fetch will be 2 hours after that.
Fixed bug where some kinds of multi-line RSS/XML sites weren't being parsed correctly and thus never produced new headlines.
