beta 15 - Some UI upgrades. And death.

Area selection UI reworked. Ailment logic improved, now having death implemented! And overall polish here and there.

Although a whole lot of bugs got fixed, there are likely to be new ones lurking somewhere. So proceed with caution and please report what you find. Suggestions and other feedback are welcome!

After this release the overall plan for the near future is:
- fix bugs
- continue polishing the UI
- write help entries and the 3rd tutorial
- add  a one or two new features

And if all that goes well then we should be ready for the public beta release.
Thanks for your patience. Thanks for your support!
