Outside map + interactible tiles

[NoraTheTurtle]

• Add new tilesets to draw the outside of the map (houses + trees + extras)
• Add tiles to define where trees can spawn after completing all tasks for a npc
• Add collision tiles to block off areas users can't go (makes map feel more 3d less 2d img)
• Add tile to define where npcs can walk after "joining society"
