Query for end result of contract verification

[TimDaub]

Even though an upload might be successful, a verification might not. Etherscan will return

{ status: '1',
  message: 'OK',
  result: 'xnzcdbmv4i1ibmnryn5x1mh5vzn2jji4t9bkfvxjbtca92wyid' }

But the contract doesn't get verified. We should query for successful verification. There's a jquery snippet for this here: https://etherscan.io/apis#contracts

//Check Source Code Verification Status
    $.ajax({
        type: "GET",
        url: "//api.etherscan.io/api",
        data: {
            guid: 'ezq878u486pzijkvvmerl6a9mzwhv6sefgvqi5tkwceejc7tvn', //Replace with your Source Code GUID receipt above
            module: "contract",
            action: "checkverifystatus"
        },
        success: function (result) {
            console.log("status : " + result.status);   //0=Error, 1=Pass 
            console.log("message : " + result.message); //OK, NOTOK
            console.log("result : " + result.result);   //result explanation
            $('#guidstatus').html(">> " + result.result);
        },
        error: function (result) {
            alert('error');
        }
    });
