Fix the DEFAULT_SORT_ORDER value for media files. Changing this

is OK, because existing app will have the old value compiled in
as a literal, and so will continue to (not) work in the same
way as before. Add code to media key generator to give a leading
ascii \001 the special meaning of "sort first".
