Read scroll bar information from value interface

Old implementation reads information by analyzing
widget structures. This causes problem with scroll
bar widget in nui library as this one may have
multiple "visual" elements that are inside containers.
As a result nui scroll bar widget always have two
children.

This problem was solved by using value interface to
inform screen-reader about number of visual elements
and position of selected one.
