UI and dialog improvement

NPCs will now talk out loud when approached. There is also a pop-up for interacting and starting the full dialog with the NPC. However, there's one NPC with no initial dialog. Must come up with a way to check for that, so players won't try to activate a dialog that's not ready.

• 2 NPCs with shared "quest"
• 1 NPC with "Go see these places "quest"
• 1 NPC with Shop options. Only dialog so far.
