Fixes and stuff — Fadry Steam update #751085

Hello! Most importantly: fixed an issue that could prevent any progress in the game if a certain choice was made. This issue was first reported recently, so I hope no one else encountered it, as it forced you to reload a save to before the choice was made, losing around 15 minutes of progress. Fixed issues regarding a certain choice near the beginning of Chapter 2, including a line of dialogue repeating and the player receiving more items than intended in the form of duplicates. Gave several lines of dialogue to the barkeep in Derva. Added decorations and a minor NPC to the port in Chapter 3.
