[Autumn] Customize initial screen behavior

[metaphore]

For now there is only one way to define initial screen - set View.first for specific controller. Though this is pretty straightforward and simple way, but not very handy for some complex cases when application would like to decide which screen is the first one on its own (depends on current data state or for debug purposes). Anyway, it would be nice to have an option to customize InterfaceService#initiateFirstScreen by changing default behavior with something similar to StandardViewResizer or StandardViewShower.
