Hotfix 0.20.10

- Fixed feeding piles not refilled anymore after job cancelation due to lack of meat (Problem applied to many buildings and caused lots of buildings not being refilled like potentially treatment chambers, research tables and possibly everything that produces and requires resources.)
- Cold weapons (Snow canons) now have correct ice pack consumption rates, before they consumed zero (Freezing zombies is not free anymore)
- Cold weapons tooltip shows correct fire rate (cooldown) with two decimals
- Added a safety check for potential stuck humbies

Known Problems: We still have some reports regarding stuck characters, wich is hard to reproduce for us, but we are trying to figure out how severe this problem prevails after this new patch.

Further fixes include
- Fixed treatment chamber triggern missing resources status correctly
- Fixed frozen zombies not hauled due to a multi threating problem
- Fixed frozen zombie storages not being refilled by haulers

Savegame Compatibility:
If you are continuing a save from a previous version that had refill bugs, you might have to disable buildings once and enable them again, afterwards the refill bug should never appear again.
