I changed the way that Arena leaders earn donguri from holding the arena position.

Previously:
If you are an arena leader, you will earn X donguri every Y cycle.

Now:
If you are an arena leader, you will earn X donguri every 1+Y cycle.

This prevents people from sniping the arena leader position right before the arena rewards are sent out. They must hold the arena for at least 1 cycle before they can earn the reward.
