Anki add-on: "Close and lose current input ?" for sticky fields

This addon has been incorporated in anki 2.1.16. It is thus disabled for version 2.1.16 and above. This add-on ensures that Anki warns you if you close the Add Card window even if you edited a sticky field (which Anki doesn't do by default).
