Modified the comments options

Had some useful feedback that it was very difficult to leave feedback (had to have a WordPress.com account).  Cutting a long story short, it motivated me to do a bit of searching and I found that I could deactivate that requirement.

You still need to enter a name and email address (trying to keep spamming down), but hopefully it will make commenting a bit easier.  I will keep reviewing the situation, and slowly we will fine-tune this to a lean mean blogging machine (yeah, ok, lame).
