Ring with trainers' calls, rematch them and play the radio (Closes #30)

Every registered trainer's callee and caller scripts run, with the
missing specials and commands (RandomPhoneWildMon, RandomUnseenWildMon,
swarms, gettrainerclassname, Kenji's break, the Blue Card and Buena's
password variables). Fight counts are saved, so rematches and gifts work
on every open map, and the daily reset clears the phone's flags.

Random calls follow CheckPhoneCall and the 20/10/5/3-minute call timer;
received calls ring twice with the caller's name, and calls play their
ringing, hang-up and no-signal sounds. Grass and fishing swarms use the
swarm tables.

The radio ports PlayRadioShow and every station frame by frame, with its
music: the Pokégear's radio card tunes by knob, house radios play through
MapRadio, and Buena's show takes the day's password for Blue Card points
that her receptionist exchanges for prizes.

 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. Fly opens the Fly map to choose a town you have visited, Teleport returns to the town of the last Pokémon Center you entered, and Dig or an Escape Rope leads out of a cave through the entrance you last used. 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. POKéDEX lists Pokémon in Johto order up to the last one you have seen. Open a seen Pokémon to read its number, category and footprint and hear its cry (CRY plays it again); once caught, its height, weight and two pages of text appear. Your name in the start menu opens the trainer card: your ID, money, Pokédex count and play time, then the Johto leaders with the badges you have earned. OPTION sets the battle style (SET skips the offer to switch when a trainer sends out the next Pokémon), the sound (mono or stereo) and the menu account (the start menu's descriptions); text speed, battle scene, print and frame are kept for later. 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.
