Core Contracts Release 12

This is a routine core contract release following the release process. This release prepares the contracts to follow the specs for the upcoming Celo L2 hardfork.

Includes migrating away from the current Celo precompiles, implementing the staking system fully in Solidity. The contracts are designed to automatically change behaviour after the L2 transition, so impact to the end user and developers is expected to be minimum. In the upcoming release, after the transition, this behaviour will be removed and contracts will always assume they are working on an L2.

This release also deprecated GoldToken and LockedGold registry entries, in favour of CeloToken and LockedCelo, created in CGP-155.

Deprecated contracts:

1. GasPriceMinimum.sol: 1.2.0.1 => 1.2.1.0
