Update data-es6.js for Traceur improvements through Aug 5.
Merge pull request #183 from webbedspace/kq

Updated Konqueror results to 4.13
Fixed the Node testing script

Fixed some things in the tests and the Node testing script that
prevented it from completing.
Node test: replace Colors with Chalk

The colors module, used for colouring console output, clobbers
String.prototype's native methods, causing the "String.prototype HTML
methods" test to fail falsely. The module Chalk is a drop-in
replacement without prototype extension.
Updated Node-harmony ES6 results
Merge pull request #185 from webbedspace/node

Updat Node harmony results, and fix the Node test script
Added 2 extra let tests

These tests check for the temporal dead zone, and correct for-loop
iteration bindings. They are distinct from the basic let-test, as they
represent more advanced or nuanced functionality.
Altered the TDZ test to include const

Both const and let are subject to the temporal dead zone.
Fixed a small bug

Also updated IE11 support for for-loop iteration scope.
Const test now checks that assignment is an error

Assigning to a const should be a syntax error. This commit does not
update the test results to match this stricter test, yet.

This also fixes tabs introduced in previous commits.
Updating const results

Almost everything fails this updated test by treating const reassignment
as a silent failure instead of a syntax error.
