Spells can affect a characters speech and their appearance.
All spells should create attributes with a 'effect' category,
and spell scripts will clean up after they are stopped.
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
