New site features

I've updated a few features on the site, particularly I've had to remove the snowflakes animation as it was slowing the performance of the system that was browsing the site - not good for usability!

I've also added a more friendly settings panel as pictured:

When the settings button is clicked this appears as a modal dialog like a lot of other features across the website.

I've also changed the search box, and whilst it looks the same, it is far easier to maintain and should appear better on older browsers, including old versions of Firefox and IE.
