Visualizing skip on test.winehq.org (and getting rid of visible desktop border)

[Paul Vriens]

Hi,

currently all tests on test.winehq.org show the blue border to indicate the test 
is running on a visible desktop. I think we can get rid of this one as winetest 
will not run if we don't have a visible desktop.

My idea is to visualize the skipped tests by using the blue border at the single 
test level to indicate tests are skipped (see attached picture).

Comments, idea's, thoughts?

Cheers,

Paul.
