v0.8.0: various bugfixes and small functionality tweaks:

- ankhs are now blessed when thrown into water of health
- demon spawners are no longer removed by unblessed ankhs
- golems now interrupt the hero when teleporting them
- fixed mimics not revealing themselves in some cases where they should
- tweaked when a space is considered open for large enemies
- fixed further AI weirdness with retreating characters
