Executed - Proposal #22: Governance and rewards patch after exploit

This proposal seeks to patch the vulnerability which allowed the recent exploit to occur and also rebuilds infrastructure which was incapacitated by it. Major changes: 1. Adding protection from metamorphic contracts to Governance voting process; 2. Redeploying Governance Staking proxy contract to nullify bugged rewards; 3. Return of tokens lost due to a bug in Governance Staking; 4. Redeploying Governance Staking logic contract and Relayer Registry logic contract to change the staking address to the current one.
