If we change variable lists they should get their own formatting in the xsl
and css stylesheets.

That will make this look different from the trigger variable lists for other
languages (which typically don't list type), but I think it's worth it to avoid
the boilerplate which is a bit annoying.

Another thing we should change while there (but it's not directly related to
this patch) is that we document TG_RELID and $TG_relid as "object ID" but
TD["relid"] and $_TD->{relid} as "OID". Punctuation of item descriptions is
also not consistent.
