Site design update: back to the default skin

[tiyire]

It was helpfully pointed out to us that the new skin has severe accessibility issues when changing the font size. We're sorry we missed it during our initial testing phase. For the moment we've reverted to the default Vector design until we get this fixed - which we hope will be soon, but could be in a few days.

Thanks to everyone who reported bugs so far! We are working hard to resolve them. Once the changes slow down or by next week we'll make a list of known bugs and some features.
