Switch to launch with SceneDelegate

Pretty sure I'm meant to launch via SceneDelegate now, was confused by
that probably due to older tutorials. Read a bit about it and it seems
like it's due to multi-instance/screen support, so switched back to
doing it this 'new way'.

Was a bit confused but I think I deleted too much from Info.plist and
got rid of the 'Default Configuration' which launches the SceneDelegate.
I think we're good now though, had to reference a new template project.
