Added Brightbox

Since some people- Ron from FTW foremost told me that the blog was making problems while loading I began to research on it. I found out that the problem was not the template itself but my lightbox implementation. I have since then changed my template and now found the time to look for an alternative. I found it with Brightbox. It's friggin fast, quieet simple and relieves me from the need to alter all my picturelinks. The only drawback is, that it doesn't support galleries at the moment. Anyhow- if you experience problems with it please let me know.
