Next lump of top work. Add -o DISPLAY_FIELDS -k FALLBACK_SORTS -s SORT_BY plus
the start of -h HEADER (mostly parses text, but doesn't display %ESCAPES yet).

Added UP, DOWN, and R keys.
Made only iotop STAYROOT (not top), added comment explaining why.
Bumped iotop's historical -O and -K to capital letters.
Added quick_ko() to add argument list from string instead of arg_list.
