Two different definitions of PotLike

[Pet3ris]

Hi There,

DAIInterestRateModelV3 and CDaiDelegate now have two different implementations of the Maker PotLike interface with the same name.

DAIInterestRateModelV3.sol

contract PotLike {
    function chi() external view returns (uint);
    function dsr() external view returns (uint);
    function rho() external view returns (uint);
    function pie(address) external view returns (uint);
    function drip() external returns (uint);
    function join(uint) external;
    function exit(uint) external;
}

CDaiDelegate.sol

interface PotLike {
    function chi() external view returns (uint);
    function pie(address) external view returns (uint);
    function drip() external returns (uint);
    function join(uint) external;
    function exit(uint) external;
}

Generally, there seems to be a practice of renaming old interfaces/contracts using versions to avoid confusion and conflicts within compilation/flattening tools - I wonder if this should be applicable in this instance as well?
