More Spam Related Changes

I’ve been getting some complaints about the “captcha”, even though I shortened it down to 3-5 characters, so I have removed it! In its place, I am running Spam Karma 2.1.

I am going to also attempt to re-allow trackbacks and pingbacks. As long as I am not bombarded by spam, I will leave them open.

Thanks to J.W. for the suggestions!
