Improved the accuracy of combat-safeties and other minor changes

Improved the accuracy of combat-safeties. They now include food cooldowns into the computation when it's a close call. Tackling the frustration of being forced to stop when you were sure you could make it
~~Combat safety no longer checks for 25% health, as it no longer has a benefit for the formula and could potentially lead to false-positives with low maximum health~~ (Temporarily disabled with a hotfix as it introduced an unintended side-effect)
Experience earned now shows decimals in the reincarnation screen tooltip and generation history, if relevant
Slightly changed how the renderer picks up completions of the chapter eight meta-unlock, aiming to tackle displayed values occasionally being out-of-sync
Fixed a bug that caused a late game exploration to remove food resources, when it should only remove construction resources
Corrected some minor textual issues
