Some JavaScript source files are only relevant in the context of the
Test262 website. They should not be explicitly included by individual
tests, so their presence in the `harness/` directory alongside "include"
files is misleading.

Move the scripts to a location within the `website/` directory to
better-reflect their intended use. Update the relevant HTML templates
with the new locations.

1. use negative regex (instead of ".") to check iframeError
2. make Test262Error.prototype.toString() always include
   the string Test262Error (no spaces) so it matches /Test262Error/
3. modify check for supportsWindowOnerror - require that
   first argument (message) to onerror() contains the error name
   by checking for /Error:/.

Change (3) above forces IE11 onto the !supportsWindowOnerror path.
Test262 tests are run inside an eval() on IE11, and errors are
caught and explicitly have toString() called.  Without this,
IE11 passes only the `message` property to onerror(), and regexes
that expect to match error name fail.

sth: revert to simple `onerror` checking

gs: refactor function `$DONE`

refactor logic tree
add support for async test failures

ed.js: crude support for error typing

S8.7.1_A2: cache result of delete

`delete` has a side-effect and its
return value depends on this; cache result of
delete so when reporting result, we are always
reporting the result that made us fail, not the
result of a new delete
[pedantic]

ed: explicitly pass cooked error to $DONE

gs: only let $DONE be called once

All Microsoft-contributed *.js and *.py sources now have Ecma's copyright header.

Laid down the groundwork for a console-based test runner.

exact error type, but we should get the '.message' property.

Generate the 'id' property from the 'path' property.

- a lot of JS harness code written in strings have been moved out to actual physical files
  such as ed.js (syntax error detection for globally scoped tests) and gs.js (global scope test
  case validator).  This change makes it far easier to maintain the test harness code
- reorganized helper.js providing a clear indication which methods are used by external objects,
  which are implementation details, and which are unequivocally test262-specific.  I've also added,
  openErrorWindow, which will be used to open a descriptive error message window for each test case
  failure reported on the 'Run' tab
- improved the error message for syntax errors occurring when a test case fails to load
- sta.js no longer tries to pickle all helper functions it contains!  Instead, we load the file
  directly from sth.js.  The performance of fnGlobalObject has been improved.  Finally, the ES5Harness
  object has been moved from sth.js (in a string) to here
- sth.js now has a browser implementer hook, controller.implementerHook, which allows browser implementers
  to handle test case failures in their own way (e.g., log to the filesystem).  The 'run' function was
  basically re-written

Added 37 new test cases from the "IE Test Center" Build release.  There were 14 modifications to
existing test cases as well.  Refactored SputnikGlobalScope.js such that test case paths are now used
as indices into the GlobalScopeTests array.

TestCasePackager.py had the concept of templated test harnesses introduced - see templates\runner.test262.html.
Also added support for one HTML test harness per ES5 chapter.  Last but not least, TestCasePackagerConfig.py
now has a 'source control' abstraction class which abstracts away source control adds|edits when dynamically
generating *.json and *.html test chapters.
