cleanup some closing logic...

cleanup some closing logic * Single prompt on quit event * Disabled leaving the kernel running on window close, as it doesn't make as much sense now that there are multiple kernel windows * Tabs respect confirm-exit setting * Removed some obsolete kwargs from MainWindow.__init__, that are no longer used Closing logic is still a bit wonky, depending on the ordering of tabs closed (masters, slaves, etc.). also fix some spelling errors, and remove errant semicolons
