Bug 9052 - rewrite the YUI links to use the system library

This uses libjs-yui to provide the skin.css and reset-fonts-grids.css
files from YUI. It patches the CSS files to point to the right location
for the files.

To test:
* Build a package with this patch included
* Install it
* Look at the OPAC and note that things no longer look terrible, and
  that there are no 404's coming from bad CSS URLs.

I created a package of 3.10+9052, installed and tested.
I confirm that the OPAC does not look broken anymore
and I could not find 404 errors with Firebug.

I also created a package of 3.10+9052 and removed libchi-* from the
debian/control file. The OPAC shows no problems using those packages,
layout, pictures and colors seem to all be in place.
Also the OPAC on master with patch applied still works as expected.
