Bukkit

I'm releasing this version just to add one function which I think is needed. Now stores will buy and sell partly-broken tools with a discount equal to the durability percentage.

Note that I am in the middle of rewriting parts of the code. Some of the commands now have slightly improved help options, but otherwise this makes it more likely for bugs to turn up. If you encounter one, please report it in the Tickets section and I will get it fixed. If you're wondering something, feel free to ask in the comments :)
