Implement Ownable interface, with different semantics

[EGreg]

1. Please rename isAccountHasRole to hasRole, and all calls in our repos to it

2. Implement Ownable interface exactly as OpenZeppelin ABI suggests, but semantics are different:

• owner() returns the first address in getAddresses(OWNERS_ROLE)
• isOwner(address) returns hasRole(address, OWNERS_ROLE)
• transferOwnership(address) will grantRoles([address], OWNERS_ROLE) and then revokeRoles(msg.caller, OWNERS_ROLE). There is no need to have transferRole() function because normally no one can transfer their own roles unilaterally, except owners. Instead they manage roles under them.
• The function renounceOwnership() will simply revokeRoles(getAddresses(OWNERS_ROLE), OWNERS_ROLE) from everyone who has it, including the caller. This function is irreversible. The contract will be ownerless. The trackers should see the appropriate events/logs as from any Ownable interface.
