Blog updates

• You can now preview your comments, perfect when you post code :)
• IE refresh bug has been fixed (or at least, I can't reproduce the error)
• Google search in the right corner should now always work
• Script tags are escaped in comments

On a side-note: At BiRC I'll again work on Skeletonz. I have learned a lot about coding and design while working on Todoist and I'll try to update Skeletonz with my new knowledge.
