- Abstract SPDatabaseDocument's Connection/.spf saving/loading functionality into state setting and getting functions, and refactor old commands to use them

 - Fix restoring of content sort column order and selected indexes
 - Add menu items for duplicating current tab (as an alternate), opening selected table in a new tab, or opening selected database in a new tab
 - Clean up file menu by making Connection/Session "Save as..." menu items alternates
 - Update localisable strings
