Previously, a Fade transition would only affect a view if its parent hierarchy was not also affected between the start/end states. This caused problems for views which were removed from their parents between scenes when their parents' visibility also changed between those scenes. The effect would be that the transition would fade the parent... but the child would no longer be in that parent, so the user would just see the child view blink out. This fix ensure that views are faded appropriately by fading them regardless the parent hierarchy; if a view is removed from its parent, fade it out. Additionally, if that view has not been removed from its parent, but its parent is no longer parented *and* scene being transitioned from is based on a layout resource file (and thus the views are considered temporary after transitioning), then it is removed from its parent to be faded out in the overlay. Also, renamed TextChange to ChangeText to be more consistent with other transition class names. Change-Id: I4e0e7dfc9e9d95c7a4ca586534b6d204c4f3bae0
