XF 1.5 Help pages through the ACP

[MJ0730]

I'm trying to mimic the styling of the default help pages with my created help pages and having some problems. Specifically, I'm trying to copy the layout of the trophies page. I get it very close but some things are off. It looks like basehtml class is being automatically added to the pages I create and messing things up, but it's not applied to the default ones. Can I override that, if that is indeed the problem?
