[webkit-dev] can we stop using Skipped files?

I'm all for getting rid of ORWT. I've observed some wrong code paths there
that are probably not even used anymore. It makes more difficult to hack on
a code which almost nobody uses and whose part of it is wrong and

NRWT is not that easy thought, but I see the unittests as an improvement.
So we can keep the same standard of the rest of webkit contributions of
writing a test to keep the behavior you're introducing.

I would like to help on removing qt dependency of ORWT.
