BEBF: Print a list of strings
Used by the routines at game_over_summary and game_complete_msg.
Prints each string at its position in its colour. The first list printed after $5BB8 is cleared also draws the border and copies the buffer to the screen; later calls only redraw into the buffer (and write the attributes directly), which is how the menu can update its flashing lines every pass without redrawing the screen.
