While I consider Polaris' character setup screen to be mechanically better
than most others, it wasn't prettier. Well. It was a bit. But now it's
more pretty-er.
Used the fake NanoUI 'browser' datum to render the pages for the New
Player panel and the Character Setup screen.
Also allows gear tweaks to take up a whole row on their own, due to potential length.
Also fixes a couple of incorrect && logical operations. Should have been ||.
