XWIS Query

Ok, that took much more time than I thought, but the XWIS pages are working again. The avarage query time is 0.8 seconds (as seen at the bottom of the page), which is slower than on my home server (0.2) :(. Let's hope it has a bad day now :)
The advantage is that this one seems not to have a bug that we had before: a blank page would sometimes show up. I think that's due to the different way of connecting to XWIS.
