Crate ab_system_contract_simple_wallet_base

A simple wallet contract base contract to be used by other contracts

It includes the core logic, making contracts using it much more compact. The implementation is based on [schnorrkel] crate and its SR25519 signature scheme.

It abstracts away its inner types in the public API to allow it to evolve over time.

The general workflow is:

• SimpleWalletBase::initialize is used for wallet initialization
• SimpleWalletBase::authorize is used for authorization
• SimpleWalletBase::execute is used for executing method calls contained in the payload, followed by SimpleWalletBase::increase_nonce
• SimpleWalletBase::change_public_key is used for change public key to a different one
