Add account components 386-405; Reduce setting, PinInput Cmd+V

Twenty account components: SettingsList, OptionCycler, KeyBindings,
ControllerMap, ProfileCard, CharacterCreator, LoginForm, PasswordGrid,
SessionList, LanguagePicker, PalettePicker, VolumeMixer,
DifficultySelect, AccessibilityOptions, AccountSwitcher, PlayerSelect,
TwoFactor, About, PatchNotes and FeedbackForm.

The components never check credentials, and no secret reaches the log:
LoginForm reports Submitted and the caller counts Failures; each new
failure clears the password, refocuses it, shakes the form and names no
field. TwoFactor builds on input.PinInput and drains an epoch-aligned
period bar. PalettePicker draws each tile in its own palette on a
pixel.Pad grid.

pixel.Settings.Reduce stills motion like the system preference, the
micro font gains '?', display.Face draws avatar faces anywhere, and
input.PinInput pastes on Cmd+V as native hosts send it.
