Settlement Button should only be available after dispute liveness finished

The settlement button should only be visible when the action is actually available.
For that we will probably have to listen tot he appropriate event on the Optimistic Oracle contract.

This feature is now merged in. Close?

Nope, this is the only filter we are still missing.
Not done yet.

The filters for expire, mint, redeem are merged but not for settlement post expiry
