Knight Lore: Routine at BA29

Used by the routine at game_complete_msg.

Clears the screen and its buffer and writes the six-line summary -- time taken, percentage of the quest completed, charms collected and an overall rating -- then fills in the numbers. The text goes into the buffer at screen_buffer while the attributes go straight to the screen, so nothing shows until print_charms_and_show copies the buffer across.

The rating is one of eight words from rating_tbl. Bit 0 of $5BC3 (the quest finished) picks the better four; bits 5 and 6 of $5BC6, the number of rooms visited less one, pick one of those four. So the rating moves up a step for every 32 rooms seen, and a player who finishes having seen more of the castle is rated higher than one who took a short cut.
