Port the trainer card and the play time

The player's name in the start menu opens TrainerCard: page 1 with the
name, ID, money, Pokédex count and play time, page 2 with the Johto
leaders and the badges owned, turned and closed with the original
buttons. The card picture, leader faces and animated badges come from the
ROM with _CGB_TrainerCard's palettes. GameTimer now counts the play time
from the end of the introduction, capped at 999:59:59, and saves keep it.

Closes #23
