Fights no longer reload the whole page after every move.

• Starting a fight, choosing a weapon, defending, escaping and picking Leave, Mug or Hospitalize now update the fight screen in place, so each round shows up in a fraction of the time it used to take.
• The fight screen dims briefly while a round is being worked out so you can see your move went through.
• If anything goes wrong, the page simply reloads as it used to.
