Picker unselect

[acaliaro]

Description

It seems that in the Picker it is currently not possible to reset the selection (the only way I think is by code, by setting SelectedItem to null).
It might be useful to have an X (as with the Entry control) that pressing it resets the current selection

Public API Changes

Maybe a property to show or not show the X

Intended Use-Case

Reset the current selection in a Picker
