Humerous [Small QoL Update]

Been a hot minute since I've touched this game! Here's the additions and changes made for Humerous:

• Added a dialogue explaining controls.
• Added titles to the roads you're in.
• Fixed something in an interaction where "Grolb" asks you to call them by "Glorb", causing some form of confusion.
• Tiny interactives in the area of Grepa's house.
