Minor Post-jam Updates

Added some minor post jam fixes and updates. There's still more to fix and a lot more that needs to be filled in for the game to be completed, but it's better than the first jam version.

• Fixed the music restarting every time you change scenes
• Made it so that multiple inventory items cannot be selected at once
• Added an animation to the move arrows
  
• Altered the billboard message so that it does not directly tell the user to use the knife
• Added a message for clicking the door (which I can't believe I missed the first time)
• Some other minor tweaks to messages and visuals

What's left to do. Firstly, I need to make the inventory items invisible and inactive until after they are picked up. GDevelop does have built in inventory code, which I am going to look into for this. Once that's done, I need to add some more areas, inventory items and puzzles to solve.

Thanks to GoedWare for creating this jam and everyone who commented and gave feedback on the game :)
