Comments changes again

Two changes, that only coincidentally happened at the same time.

First change is I added stickiness to the name and URL fields for comments. Those who use their own computers and don't obsessively clear cookies generally won't have to retype them. There's also a preference related to ads available if they show up, but they don't for recent posts anyways...

Second is I removed the xbl check for comment submission. It has blocked several thousand junk comments over the past few months, but about a third of the junk gets past it anyways. The next check isn't really any more resource intensive, and it will probably catch them too. Because it's probably not needed, and it hit a false positive today (unless people are putting odd names, the first in almost 8 months since I started logging failures). It was a nice check to have since it's hard to avoid (a smarter script won't help), but hopefully not necessary. If I see spam, I may put it back temporarily and devise another workaround.

On an unrelated note, sorry for the lack of posts lately. I've been busy with other things, and trying to keep my sanity by eliminating extra things. Hope things are going well for everyone.
