Did a bit of refactoring on the test262 directory structure and propagated changes from

website\* out to test\*:
- Removed test\harness\ECMA-262-TOC.xml.  The casing on this file was incorrect, but
  more importantly it's a static file not generated by the harness
- Populated test\harness with the contents of website\resources\scripts\global\.  In
  the future, we need to update test\harness\* and propagate these changes out to
  website\*
- Test\suite\ietestcenter is now a verbatim copy of the IE Test Center tests that
  WERE under website\resources\scripts\testcases\*
- Moved all Sputnik tests from website\resources\scripts\testcases\* out to
  test\suite\sputnik_converted
- Moved website\resources\scripts\testcases\excludelist.xml out to test\config\*.  This
  particular file was only used for the test conversion process to XML, and is not actually
  needed by the website as best as I can tell
- Website\resources\scripts\testcases now only contains the XMLized test cases.  This is
  the right thing to do as the *.js files here weren't actually being used by the website
  and the general public can now peruse the test cases directly via Mercurial
