- Make the DBView window the document window. This allows the document to be closed when the window is closed, freeing the document's memory

 - Update a number of dealloc methods to include more retained memory, and to avoid releasing non-retained memory
 - Remove notification observers and delegates where appropriate to avoid issues after document closing
 - Fix a couple of memory leaks
 - Support window cascading for all windows past the first, using the first window as the autosave window
