recent updates. fixed by making it so that when an error is received by invoker, the error message is displayed but the callback is
not invoked
- bug: if you get an error when saving a note, the note should not disappear. it should still be present so you can try to save it again - make invoker not call a callback if there's an error
- in Wiki.hide_editor(), only close an editor after save_editor() has invoked a provided callback function
- make sure this doesn't break the note conflict notification error (saved editor should still shutdown)
- test this in IE
