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.
