Update the banner text outside the rules page, too.
Implement most of the simple rules changes.

More complicated stuff like the new banners will be done separately.
Update the lists of uniques and combos.
Allow space-separated lists of combos and update the Nemelex's choice list.

The Nem choice list will need to be updated again right before tourney start,
of course. It's much easier to update it from Sequell output now.
TODO list for the next tourney.
