This commit gives an "AI" capability to any object (still
triggered by the 'say' command), so now the Wee Beastie can do more
than purr.
Also fixes the Witch and the Dragon's movements throughout the Realm.
We can also Scry into rooms in order to watch the behavior of the Chatbots.
Also fixed many bugs and inconsistencies. Including:
- Whisper works with RP system
- Saying /to to non-player character just uses what they wrote
- Minor yell bug
- Actions on Things (like the puddle) work with RP system
