qt: Remove checkbox for passphrase formatting
* qt/main.cpp (qt_cmd_handler): Pass changed formatted passphrase options to the dialog. * qt/pinentrydialog.h (PinEntryDialog): Add field mFormatPassphrase. Remove field mFormattedPassphraseCB. (enum PinEntryDialog::FormattedPassphraseMode): Remove. (struct PinEntryDialog::FormattedPassphraseOptions): Remove fields mode, label, tooltip. Add field formatPassphrase. * qt/pinentrydialog.cpp (PinEntryDialog::PinEntryDialog): Initialize mFormatPassphrase. (PinEntryDialog::setFormattedPassphrase): Set mFormatPassphrase. Update widgets. (PinEntryDialog::toggleFormattedPassphrase): Use mFormatPassphrase instead of state of removed checkbox.
This simplifies the formatted passphrase feature by removing the
possibility to enable/disable the formatting on the fly. Formatting
is now controlled exclusively by a configuration option.
