Blogroll updates.

I've done some updating of the blogroll.

I've added The Wizards Ball and The magic square. I've also removed a few blogs that aren't getting updated very often.

It may surprise some to see that I've left MagicRants listed on my list. Steve says some good stuff, and some stuff I obviously don't agree with, but that's what having opinions is all about. I'm not going to make up new policies that give me a way of avoiding issues.
