Runs tests on IE11 when requesting IE8, 9, or 10 on Windows 7

[mezz]

Using the following browser statement in Dalekfile.json

"browsers": [
  {
    "ie8Win7": {
      "platform": "Windows 7",
      "actAs": "internet explorer",
      "version": 8
    }
  }
],

Run any version of the ie browser (8, 9, 10), and it runs ie11 instead.

> dalek test.js -b ie8Win7 -d sauce

Guess that is a problem in delivering the browser version contents to Sauce. I´ll investigate.
