• filesigndlg.c (gpa_file_sign_dialog_set_force_sig_mode): Forcing

affects visibility now instead of sensitivity.
(gpa_file_sign_dialog_set_force_armor): Likewise.
(gpa_file_sign_dialog_constructor): Allow sig mode frame to be
hidden. Don't hide armor based on UI expert level. Never show
the cleartext sig mode option.
