Update the docs to fully reflect the aaa changes by linking in the new
modules and removing the deleted ones; renaming mod_auth_anon->mod_authn_anon,
and mod_access->mod_authz_host.

All docs to the old modules are now deleted.

Translations were kept with their old modules.  (Can't read Japanese.)
