Save gas by using a ParameterizerInterface in Registry

Presently, Registry.sol imports Parameterizer.sol in its entirety, but only calls the function get(string _name).

You can save gas and storage space by using a ParameterizerInterface.sol in Registry

interface ParameterizerInterface {
        function get(string _name) public view returns (uint value);
}

I believe the same is true for PLCRVoting
