DevZenDAO: prepare all auto methods

[AnthonyAkentiev]

https://github.com/Thetta/DAO-Templates/blob/master/contracts/3-DevZenDao/DevZenDao.sol

Each method with isCanDo() should have the auto caller:

function updateDaoParams(Params _params) isCanDo("DevZen_updateDaoParams") public {
  super._updateDaoParams(_params);
}

// TODO
contract DevZenDaoAuto is DevZenDao {
   // TODO
   function updateDaoParamsAuto(Params _params) public {}
}
}
