Demo 0.1.8 : Death is not the end

Based on your feedback and further testing on my part, I decided to make death in battle less punitive. On the other end, I hope it doesn't make the game too trivial. Feel free to tell me what you think about these changes.

Patch notes

• Wound system : when a characters falls in combat, he now becomes wounded instead of dying immediately. Wounds reduce Max HP, heals over time, and can kill permanently the character if he has too much
• A new world site : the "Dark Church" which allows to resurrect dead characters for a fee
• A new Unlocks window on the main menu to keep track of the achievements
• As always, some various minor bug fixes and UX improvements

Thanks and have a good day!
