show/hide tabular winners in JS, not Python

[artoonie]

The ability to show only winners in the tabular option was presented as a GET setting (i.e. one that could be changed by an end-user, not an uploader), but in reality, it was done in Python and therefore only respected when selected by the uploader. This PR makes it happen dynamically instead.
