Port the Pokégear, phone calls and Mom's bank

POKéGEAR in the start menu runs the clock, Town Map and phone cards with
the original joypad rules. Calls to Elm and Mom run their callee scripts,
with the out-of-area and out-of-hours cases and HangUp's corrected timing.
Mom saves a quarter of trainer prizes once asked, talking to her at home
opens BankOfMom (GET, SAVE, CHANGE and the DST checks) with its digit
amount box, and MomTriesToBuySomething buys items and dolls with her
savings. Saves gain Mom's money, her next item and its trigger balance.
