TPOF Stability Update

Minor Update to TPOF:

• Renpy has been updated from 7.4 to 8.0, hopefully this will improve performance

• Ice and Blood overlay transitions have been simplified [ old code was hacky and unstable ]

• Added in persistent saves throughout to prevent players from losing progress if their game closes improperly [ closing a laptop without shutting the game down, losing power, game crashes, etc ]

Please let me know on twitter @HumanGatobob if you experience crashing or an error due to this update- the Renpy update required some code fixes <3
