Title: Extend hidden check to use also alpha value

Use also alpha value as indicator of view visibility. Resolve #514 when system back button indicator for root view controller is on the view, has hidden = NO but alpha = 0. In current versions of iOS views with alpha = 0 are not intractable, so should be considered as hidden, because user/KIF cannot interact with them.
