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.
Begins breaking down the large character setup in more manageable modules, allowing for easier additions, edits, and removals.
