cosmetic changes
- Added skeleton for control message type
- Created postmaster to handle message types as callbacks
- Began to move system over to using postmaster callback methods (but is not complete)
- As part of move, made XFER_DATA_COMPLETE message to know when file ends (easier for callback)
