Carl's blog comments

As per the message on SO chat here is my first attempt at a command to parse the comments from Carl's blog. It does create a new temporary file - blog-last-updated.r3 - in the same folder as the bot to store the date-time of when it last ran. All in all it has been great fun trying to do this and I am up for finding another (simple) Rebol challenge to start on next.
Thanks for making such a great bot.
Cheers, John
