Cleaned up Catagories

I spent some time and cleaned up the categories on here. I had way too many and the cloud in the sidebar was very cluttered. I think it looks a lot nicer now.

I also added a random post link in the sidebar, so if you want to check out some stuff on the site but don’t really know what to look at you can just click there and get thrown to another one of my wonderful posts. Try it out I think its pretty cool.
