Port the introduction's naming and clock screens

A new game now runs NewGame's InitGender and OakSpeech natively before
the bedroom: Boy or Girl, InitClock's hour and minute steppers with
their YES/NO confirmations, Oak's speech with Wooper, and NamePlayer's
preset names or naming field (a blank name takes CHRIS or KRIS). Texts,
menus and time strings come from a new INTRO profile table verified by
check:reference; Oak's and the player's pictures decode from
TrainerPicPointers, ChrisPic/KrisPic and TrainerPalettes.

The chosen time is kept as a minute offset from the device clock, which
time of day, the weekday, NPC hours and the daily reset now read. The
intro runs only when nothing is saved; a save made during it starts it
again. Saves gain intro and clock.minuteOffset, migrated by absence. The
shell's name and character fields are gone. Intentional change: the
steppers start at the device time rather than 10:00.
