Show the level select option used to start the level in the pause menu.

Previously, level select only appeared in the SP pause menu if you load a complete save file.

Now, entering the game through an Extras menu level select shows that level select. Simply makes it more convenient, as you don't need to exit to the main menu again whenever you want to get to another level from an unlocked level select.

Tested all ways you can start a new map from the menu that I can think of (New Save File, Complete Save File, Mid-game Save File, several different Level Select types, custom Warp, Record Attack, Marathon, Tutorial), and could not smuggle wrong level selects into any.
