* grub/asmstub.c (console_translate_key): Deal with KEY_PPAGE
	and KEY_NPAGE.
	* stage2/serial.c (serial_translate_key_sequence): Added two new
	codes for Page Up and Page Down.
	* stage2/asm.S (translation_table): Added entries for KEY_PPAGE
	and KEY_NPAGE.
	* stage2/stage2.c (run_menu): Deal with Page Up and Page Down.
	Also recognize the right key for the selection of a boot entry.
