harness: remove unused code

sta.js:
slight change to Test262Error() semantics; message property now always set (default "")
make $ERROR a var
set $ERROR to function $ERROR so it can be overridden if needed
remove 2009 copyright in favor of 2012 copyright
REVERTED: remove never-used fn testFailed
testFailed actually used by $FAIL
remove obsolete fn $INCLUDE

ed.js:
remove commented-out obsolete code

test262.py:
remove always-included harness file that provides no functions used by any extant test
add comment line to nonstrict

cth.js: define `print` for node, cscript

use cth (console test harness) to define functions
for console runner.  V8, Spidermonkey (js) and JavaScriptCore (jsc)
provide a function `print`.  Provide a default `print` for node
and cscript

set print_handle to 'print' by default (can still override)
for cscript: wrap tests in try/catch so we get syntax errors

harness: remove unused code
Correct test assertion (Fixes issue#61)

Changed Number.isNaN_Boolean.js, String.prototype.endsWith_Fail.js and String.prototype.endsWith_Fail_2.js to test for the correct result. Also removed implicit coercion in a couple of other test files.
Correct Array.prototype.fill tests (Fixes #63)

The expected results weren't correct.
Move tests to Math.clz32 (Fixes #41)

Number.prototype.clz() was renamed to Math.clz32(). Also removed superfluous 'spec' entry in test descriptor.

Merge pull request #67 from smikes/negative-addErrorName-bestPractice

Remove negative flag from test bed. Replace with specific errors. Other misc. fixes.
ES5.S15: new tests to clarify Array.concat

Test of spec language from 15.4.4.4,
5.b.iii.3.b states 'Call the [[DefineOwnProeprty]] internal method of A'
which means that the result of Array.prototype.concat
should return `true` from `hasOwnProperty` for every property
created by `concat`, up to `length`

Set length to 3.
a[0] is set to 0 on a
a[1] is unset
a[2] is set to 2 via a prototype of a

add assertions for values of b[0], b[1], b[2]
add assertions for b.hasOwnProperty('2')

Check with Array.prototype and Object.prototype, separate tests
