fix - remove debug log spam

Fix accidental removal of functions from utility file

Add better logic to determine if distributions are adding up to 100 - Thanks to Burryaga for the contribution

Reverting last update again. If someone has time to investigate please come forward as i don't have time at this time

- Fix zombies not updating HP pool properly when on fire (fix by aortez)

Issues reported by some users lead to believe there could be some unexpected side effect from latest changes. Reverting to latest stable version until further investigation.

- remove debug logging never meant to go live, sorry guys, it's been a long day

- rework some internal logic for smart zombies in preparation for the patch that introduce management of sight/hearing
- added long memory on smart zombies

In order to improve the logic that override zombies behaviour, several internal checks have been altered or disabled due to being suspiciously too loose or too tight.
The response in how the zombies change preset when the day/night/weather cycle changes should now be more precise and responsive
