Some tests specifically concern the application of the `use strict`
directive as it appears in JavaScript source code. These tests should
*not* be run with the `onlyStrict` flag because relying on the test
runner to enable strict mode makes the semantics of the source code
irrelevant. Update these tests to use the `noStrict` flag.

Other tests concern language semantics that are only valid in strict
mode, but the mechanism for enabling strictness is inconseqential.
Update these tests to use the `onlyStrict` flag and remove any redundant
`use strict` directive prologues contained within.

Still other tests are valid both within and outside of strict mode.
In keeping with the majority of other tests, do not specify any
restrictions on the environments in which these tests may be run.

This commit normalizes the test case format used across test262. It applies the following transformations:

* Convert to YAML for frontmatter
* Remove of trailing whitespace
* Replace /r/n with /n except in chapters 6 and 7.
* Copyright header always uses // comments
* new includes attribute replaces $INCLUDE
* No implicit assumptions about test environment other than $ERROR. Everything else appears in the include array. This includes "runTestCase" which is now included in a substantial number of tests.

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

77 new (mostly) strict mode tests plus the removal of one invalid test case.

Sputnik and IE Test Center tests now live side-by-side in ch* directories under test/suite.

source starting NOW, to test/suite.

(between David Fugate and I) canonical test262 test format

assertTrue became assertTruthy. Canonical form of doc-comment attribute value source no longer have a leading colon and trailing semicolon. Any existing such are stripped during conversion.

style to append runTestCase(funcName); rather than
assertTrue(funcName.call(this)), giving the testing framework more
control.

- 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:
