[dustinxie]

Description

move the address check from inside protocol.Handle to the action's LoadProto() and SanityCheck(), which is consistent with other action's behavior

4277 added a new field address to action ClaimFromRewardingFund, and the purpose is to help other accounts to claim rewards (not claiming rewards to some other accounts).

claimTo is just a parameter name, which may be confusing. a better naming for this parameter is claimFrom.
