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.

Annex B features now listed as n/a in non-browsers

Since Annex B features are only required for browsers, non-browser
implementors now show a gray "n/a" instead of "No" when they're not
supported.

This also updates the feature-sorter code to account for non-applicable
features.
Changed listing from "n/a" to grayed "Yes"/"No"

Now, both the presence or absence of an optional feature is drawn gray,
but still shows "Yes" or "No" anyway. Thus, the information regarding
implementation status is retained, but is highly de-emphasised.

Also, gray result squares now have an informative tooltip.
Shift annex B features to the bottom

To save on maintenance (and to produce a cleaner diff), this is done
programmatically.
