Demo bug fixes and improvements

Thank you to everyone that played the Emergent Fates Re:Developed Demo during Steam Next Fest! Based on some very helpful feedback from ghostyamato I've made a few bug fixes and improvements: [list] [*] Fixed bug where forging some augments would result in Eager Spirit instead of the expected augment [*] Fixed bug where party's HP/AP would not be recovered after loading auto-save [*] Changed how loot drops are calculated which should result in significantly more drops (this includes essences) [/list] Hope you enjoy the changes.
