*neutrino menu: fix 'memory ' of selected items in submenues

Add small helper class to manage missing values
e.g. needed for deallocated widget objects.
This class we can also use for other things in future!

In this context I added a vector for 'selected' values needed for
deeper and deallocated submenues.
The identification of widgets working now with a new widget parameter named 'w_index'.
setSelected() and getSelected() functions are still working, but are not needed, if we use an index

-add define for default widget index
-add new header file for enums
-adapted many menu classes for this parameter

Hope it' works fine. If you find any menu without  a 'memory', please add an index.
