To change:
Don't have control artifact units regenerate; dissolve control
artifact and reseed once last controlled NPC dies
allow an END keyword to terminate POST/MESSAGE
add an order scanner command to MAIL a message to another unit,
so that diplo mail "from a character" may be sent without revealing
the sender's identity
Still considering:
GIVE/BUY across zero time routes
Don't see into sublocations
