Upgrade and new look

After a year and a half we decided to update our style and our software. The look has been tested on Firefox and Konqueror, so hopefully it looks ok to those of you who are using Safari as well.

A cool feature of this style is its inclusion of toggle for the sidebars which may make reading some of our long posts easier.
If there’s any weirdness in rendering please let us know and we’ll try to fix it (a screenshot would be a great help).
