Confirmation dialogs in pause nav buttons

[nitaku]

It should clarify what progress is lost:

• Skip current match: Current scores will be lost! (maybe only if the match is already started)
• Nav to minigame sel: All scores and stars will be lost!
• Nav to character sel: All scores, stars and minigame cards will be reset!
• Nav to main menu: All scores, stars, minigame cards and characters will be reset!

Or something like that
