- Add a new SPSplitView class, intended to replace all BWSplitViews and so allow us to remove BWToolKit. Supports constraints and animated collapsible subviews configured in code, fixes crashes and exceptions if a window is closed while animations are taking place or scheduled to take place.

 - Replace the two vertical splitters in the table list (the filter splitter, and the table info splitter) with SPSplitView implementations as a test
 - Add a helper method in the new SPDateAdditions
