[wwwdocs] [3/3] projects/cxx-status.html -- introduce global CSS for tables

[Gerald Pfeifer <gerald@pfeifer.com>]

And with this, colors are back again, and we nearly are done.

Jason, I suggest to color the cells instead of just the font,
alas with a lighter color, and committed this per the patch
below.  

If you'd like to make this look exactly the same as it used to, 
we can of course.

Gerald


Move color styles for "supported" and "unsupported" to global
stylesheet.  Change from text colors to lighter background colors.
