Move the title screen's extras to its corners and dock

The account chip and a quit button go in the top corners and the version
in the bottom left, now smaller and fainter. Minecraft's options and
Saturn's settings take the HUD editor's place in the dock, and the intro
brings the menus and edges in after the logo. Faded elements now start
hidden instead of at 10% opacity.
