v0.8.0: various bugfixes and behaviour tweaks:

- fixed storm clouds spreading water faster than intended
- fixed visual bugs with stealth and hourglass stasis effect
- fixed an exploit where unstable spellbook scrolls could be cancelled
- upgrading a stack of missile weapons now resets durability, just as upgrading a single one already did
- fixed visual bugs when tengu traps would be created and immediately removed by some effects
