Changes to the Sidebar

I've tried to clean up my sidebar. It looked cluttered to me, and it allows me to list more stuff. My categories might not be exact, and I tried to list the ones with the best material to fit the category (although there is a lot of overlap), and had lots of good links.

If you see websites that are listed again and again on these sites, that indicates it is a good site.

Please leave a comment in the comments section if I've made a glaring error of ommission.
