Save Note Drafts as You Type: Code Review Practice

If the app is killed while someone is editing a note, they lose what they typed. This saves the text to SharedPreferences as they type and restores it the next time the editor opens. Saving the note clears the draft. I tested it by typing, swiping the app away, and reopening it.
