Latest set of external contributions from IE Test Center. Compared to test\suite\ietestcenter:

- 26 test case modifications. Most of these involved replacing instances 'window' with the global object - removal of 47 test cases. The bulk of these were dependent upon 'window' methods or properties such as 'document' and 'alert' - addition of 1,234 new test cases. These cover the following ES5.1 sections: chapter07\7.6\7.6.1 chapter07\7.8\7.8.5 chapter11\11.8\11.8.2 chapter11\11.8\11.8.3 chapter12\12.6\12.6.3 chapter12\12.6\12.6.4 chapter12\12.7 chapter12\12.8 chapter12\12.9 chapter13\13.2 chapter15\15.10\15.10.2 chapter15\15.10\15.10.4 chapter15\15.10\15.10.6\15.10.6.2 chapter15\15.11\15.11.4\15.11.4.4 chapter15\15.1\15.1.1\15.1.1.1 chapter15\15.1\15.1.1\15.1.1.2 chapter15\15.1\15.1.1\15.1.1.3 chapter15\15.1\15.1.2\15.1.2.2 chapter15\15.1\15.1.2\15.1.2.3 chapter15\15.2\15.2.4\15.2.4.2 chapter15\15.3\15.3.4\15.3.4.5.1 chapter15\15.3\15.3.4\15.3.4.5.2 chapter15\15.4\15.4.4\15.4.4.10 chapter15\15.4\15.4.4\15.4.4.12 chapter15\15.4\15.4.4\15.4.4.4 chapter15\15.9\15.9.1\15.9.1.15
