v0.1f / First Demo Final(?) Update

actually updated like a week ago but i got distracted by touhoujam oops

Changes: 

• Unlocked save/load functionality
• Made chairs and tables destructible with dashes (necessary soulslike feature)
• Added bird and barrel NPCs
• Increased rifle rotation rate when autoaiming
• Patched some holes in level geometry
• Various UI/UX fixes (1440x900 resolution, lower-resolution UI scaling issues, "empty" label on empty magazines, getting hit knocks player out of manual aim mode)
• Various other bugfixes (jumps being shorter horizontally when toggle-sprinting, player being able to dash while using an item, audio settings not taking effect at game start)
