[webkit-dev] Test conversion to use W3C testharness.js

Is your concern that the Pass is not in all caps?

The current output looks like this:

Result	Test Name	Message
Pass	testParse: Assigned none to property, expected return = none

The pass at the beginning of the line is the test result.  Had the test
failed, this would read "Fail".

The next portion of the line, in this case "testParse: Assigned none to
property, expected return = none", is the description string specified in
the call to assert_equals.  The description can be any string that the
user specifies.

The spacing of the results when they are dumped as text obscures the
difference between the test result and description - this is something I
can address in a number of ways depending on everyone's preference.  I'll
investigate further and come up with some suggested fixes.
