menu_view: propagate widget version attr

Browse Source 
The 'Widget::_version' attribute was meant to allow the deliberate
replacement of a widget by a same-named widget by changing the version
while keeping the name, thereby suppressing any geomety animation.

However, the implementation missed to populate the attribute with the
value provided by the dialog ROM, prompting the unconditional
re-creation of the widget whenever a 'version' attribute was specified.
Even though this had the (desired) effect of preventing geometry
animations, it could cause feedback loops between hover reports and
dialog ROMs because the 'hover_changed' condition in 'Menu_view::Main'
would always stay true while a versioned widget is hovered.
