HN Blacklist -> HN Toolkit

So thanks to nirmal's brilliant idea of browsing Hacker News in split view, I got the bug last night to add that functionality to the HN Blacklist. What I had originally thought would take about two hours ended up being about an eight hour ordeal, but it was worth it. I learned lots of neat things about the browser security model and GM evaluation, all because I couldn't get some event listeners to work.

The problem is now solved, and seeing as how my little blacklist does more than just that now, I went ahead and renamed it to HN Toolkit.

Obviously nirmal's bookmarklet works for a wider variety of browsers than my GM script, but my way means you don't have to hit his server to do it, which I figure is a good thing.
