Make HTMLClass::history signature compatible to _HTMLItem::history
_HTMLItem::history accepts 4 optional named parameters. If a template
(e.g. issue.item.html) calls history with a named param and then is
called in the context of creating a new issue, you get a traceback.
Change HTMLClass::history to accept any named parameter so
adding new named params to _HTMLItem::history doesn't
require a change to HTMLClass::history.
