I've removed the mailing list archive menus. I changed the subnavbar to
write, e.g., "Download sub-menu" instead of "menu". Is that more or less
confusing, Asger? Or still the same, which is to say (IYO) very?

Note that the "Ildm sub-menu" is currently created only if using top navbar.
Obviously inconsistent, but not worth fixing now. If we do decide to use
subdirs, then we probably won't have any which aren't listed in start.php3.
