Latest 4 solc versions are missed.

When listing the remote versions the loop misses the last 4 versions in the list.

for (var i = sources.length - 1; i >= 0; i--) {
    // FIXME: use build as well
    var version = sources[i].match(/^soljson-v([0-9.]*)-.*.js$/);

    // Skip invalid lines
    if (!version) {
      continue;
    }

    if (version[1] === wanted) {
      downloadBinary(sources[i].match(/^soljson-(.*).js$/)[1]);
      return;
    }
  }
