Added a photography section

Although I've not done much in the way of weather photography I do try and snap interesting things when I see them. Because of this, and because I want to try and do more weather photography, I've added a weather photography section to my weather station website.

Giving a little back

I've added a tools section to my weather station website. The idea is to make available some of the tools I've written that make the station work (at least those that have a chance of being useful to other people — a lot of the code I've written is very specific to my setup and it wouldn't make sense to publish it).

Yet more wind compass stuff

After adding a wind compass graph to my site's graphs, and then after improving them (with a bit of help from Tim), Tim's gone and nicked the idea for his own graphs.

Not only that, he's gone and added lots of cardioid graphs too. I'm not sure what they tell me, but they look kind of fun.
