feat: hax for great justice (#14)

- Dont send message on empty
- inbox flag to override $USER
- Filter messages to only chat with partner.

NOTE: might be better to parse the message in loop to handle events outside the formatting code.

NOTE NOTE: i think we might need to revisit read recipts.. maybe including user@domain?
