Handle properly dojo._base.html.attr 2nd parameter

[tsemachh]

Hi
Ran a conversion on our code base noticednext change all across:
Old Code:
var dateFormat = dojo._base.lang.trim( dojo._base.html.attr(node, "dateFormat") || "");
Converted to:
var dateFormat = lang.trim( html.attr(node, seteFormat") || "");

This happens for all markupFacotry using this api.
thx
