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.

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.
