Adjusted the fonts again...

I adjusted the way I specified fonts for this blog. Before, I was specifying a specific size (like 12pt for the main font), but when you do that, if the user adjusts the browser to make the text look bigger, it won't work.

So now I've used relative sizes everywhere. (i.e., make the titles X% of the size of the main font, that type of thing) This should allow users to make the text look bigger or smaller, if they wish.
