Feature Description

As suggested in an earlier issue, add an OnFocusChanged() event handler to the Select component that is invoked when the highlighted option is changed.

Problem Statement

Problem 1:
The Select component does not have a way to page/scroll options and when the option list is too large it can overfill a console window.

Problem 2:
The Select component does not have an event handler invoked when the user changes the highlighted option via up/down navigation, which might otherwise provide a way to implement a scrollable window over a large options list.

Proposed Solution

OnFocusChanged() is added to the Select component.

Alternatives Considered

OnHighlightedValueChanged() could be a different name for the same event handler functionality proposed here.
