FIL Owner Actor

Implementation of owner account with FVM native actor

V0.1 for mainnet - 4/15

Congratulation to F(E)VM. It's deployed to mainnet at 3/14, we can make something really interesting with Filecoin.

For Peggy, some key features are not supported by current F(E)VM implementation. It includes

* We still cannot detect deposit of native FIL inside running smart contract instance
* Only a part of miner interfaces are exported to solidity contract, not all
* We still cannot custody worker and controll addresses to smart contract

Peggy's vision is to build protocol to custody all miner functionalities to smart contract. It will cover whole life cycle of the miner. Idealy, we don't need to run any management of miner out of contract. But if Peggy want to go ahead with currently F(E)VM implementation, we need to compromise with

* Add some preset management accounts to smart contract instance, the number of accounts should be even
* Implement a govenance machenism to let manager vote to replace management account
* Implement a govenance machenism to let manager vote to accept deposit from some address
* Implement a govenance machenism to let manager vote to return deposit to depositer

Of course, Peggy contract should be able to act as owner account, record depositers, calculate and distribute period reward. So we decide to develop V0.1 version of the contract firstly for current mainnet F(E)VM. It's not a finance protocol, it's only an accounting tools to for different share holder of a miner. It'll be deployed to mainnet soon with our test miner.
