random courses taking too long to generate with autogen disabled: it has
to iterate over *all* steps (including the unused autogen steps); when
outputting the catalog, this means it has to iterate over every song once
per random course line per steps type per course difficulty. (test case
of one 9-random-entry course with autogen off: ~10 seconds -> ~1.5 seconds;
still too much)
