b19_3: Balance Update + Smaller Fixes — Gloamvault Steam update #697413

"Enemies start with -x% HP" no longer stacks. Only the highest effect is applied, up to a maximum of -25%. It won't trigger again after fleeing. Charm chance is now capped at a maximum of 75%. Increased charm penalty buildup after level 3. Increased chance for bosses to block doors. Slightly nerfed healing (reduced gain from merging, slightly lower base values, and a smaller increase from stats). Slightly increased enemy power level scaling. Limited dropped items to a maximum of 3 effects, down from 5. Lowered percentage value caps on ability-related item effects (reduced to 25% max, down from 85%). Fixed an issue with the Merge-O-Mat and Meat Grinder consuming side slots, now capped at a 40% chance. Fixed a crash related to the Tinkerer. Fixed upgrade point notification appearing unnecessarily. Added a "Disable audio when window is in background" setting, for everyone playing at work.
