New permalinks style

As I had warned you before, I've started working on some improvements for this blog. Today, for instance, I've finally implemented the new permalinks style. From now on, I'll try giving every entry a somewhat meaningful name, like:

http://solaris.reys.net/2005/11/blog_upgrade

instead of

http://solaris.reys.net/archives/84-.html

All the old entries will be slowly converted, but old-style meaningless links should still work.
