quick frontend (app): added AUTO_RESYNC attribute in QuickApp, when set (default) the resync method is called on all widgets automatically: if AUTO_RESYNC is False, frontend must call itself the resync method. This is useful to improve performance, resynchronising all widgets at once may be resource intensive, and it may be more efficient to resync a widget only when it is visible.
