Only one round should be allowed to be active at a time.
We should probably write something in the backend to prevent saving a state that is bad (more than one round is current), but we should also guard against confusion by adding a little Javascript on the front end to ensure that the 'Round is Active' checkbox is ONLY checked for one round. If someone selects a different one, then all the others are set to 'off'.
