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

 Mr. Pokémon gives you the Mystery Egg, and Professor Oak gives you the Pokédex. Your rival challenges you in Cherrygrove on the way back, and Elm's aide gives you Poké Balls. Back on Route 29, the Dude shows you how to catch Pokémon. From then on, open PACK in a wild battle to throw a Poké Ball. Caught Pokémon join your party, and you can give them a nickname. In battle, PKMN switches Pokémon or opens a Pokémon's stats, and when one faints you choose the next. PACK's Items pocket uses healing items, revives, Ethers, X items and Poké Dolls.
 
-Start opens the start menu. POKéMON shows your party: open a Pokémon's stats, change the order, rearrange its moves, or give and take held items. PACK shows your pockets: use Potions, status healers, revives, Ethers, PP Ups, vitamins, Rare Candy and evolution stones, give or toss items, and ride the Bicycle. Pokémon evolve when they level up after a won battle (press B during the flashes to stop it), and learn new moves outside battle too. Field moves work from the party menu too: Cut, Surf, Strength, Flash, Whirlpool, Waterfall, Sweet Scent, and Softboiled or Milk Drink to share HP. In PACK, SEL registers a key item such as the Bicycle, and Select then uses it. POKéGEAR shows the clock, the Town Map card with a cursor over every landmark, and the phone: call Mom or Professor Elm. Call Mom after the catching lesson and she offers to save some of your trainer prize money. Once the Mystery Egg is delivered, talk to her at home to save or take money, or to switch Daylight Saving Time; with enough saved, she buys items and dolls for you and calls to say so. Bill's PC can move Pokémon between the party and any box. The poster opens the Town Map.

 The Pokémon Center PC opens Bill's PC, your own PC and, once you have the Pokédex, Professor Oak's rating. Deposit, withdraw and release Pokémon, and switch or name boxes. Store, withdraw or toss items. With six Pokémon in your party, a catch goes to the current box. When that box fills up, Bill calls you. The bedroom PC also lets you arrange owned decorations.
