While experimenting on the new rtsim implementation I found the commands to be missing some values that I was expecting. This adds these to the /rtsim_{npc,info} commands.

• Add the name of the NPC to /rtsim_npc to help identify this NPC in the world
• Add faction & personality to /rtsim_info command to learn more about the NPC
  • It might be better to get a list of matching traits for the personality, instead of the raw values, but I did not really know where this should go. This would effectively be similar to Personality.chat_trait() without the .choose(rng)
