Guestblock upgraded

It’s now running at v.5
Some stats are now displayed, and the page appearance has altered as a consequence. I got booted off the machine earlier just before making a couple of tiny css changes, and when I remember what they are, I’ll implement them.
Remember, the GB is still in beta, so test it by posting lots of blocks and let me know if anything goes wrong. (And yes, I need to switch the orange block on again….. when I find how to do that. Again).
Best day so far was 22 blocks. Now that must be beatable !!
