New
Fallen zombies now drop skulls on the tile where they die.
Steam cloud now works

Tent Setter renamed to Tent Settler.

Fixes
Upgrading a camp in place no longer works (yes it was not intended)
F12 no longer cycles tile fog/visibility.
The relic Scout's Outpost no longer grants a free explore on tiles that only touch a tower or a trap.
The Ballista now has a 1-turn delay (as it should have had from the start :( )
Thanks a lot for all your feedback, but I'll still take some time to rest :)
