Subject: [PATCH] * Add public wxApp::sm_isEmbedded flag like on wxMac. 
 Default initialization   to true but a plugin can set it to false to cause
 wxCocoa to not initialize   things like the application delegate or the
 menubar manager. * Fix call to [NSNotificationCenter removeObserver:] to use
 the correct object.
