This came to light due to python3 not liking try['StarPos'] =
list(this.coordinates) if this.coordinates was None. As the comment
says these three fields are mandatory, ensure we can actually set them
appropriately, and display an error if not.
NB: Due to, I assume, EDDN relay de-duplication of messages, it's been
difficult to 100% test this. No errors thrown, and stock/release EDMC
also doesn't result in a new message arriving at my EDDN consumer.

Use line buffering for replay file.
By default it takes a lot of data being written to the file for it to
be flushed. Or exiting EDMC. So, let's reduce the chances of data
loss.
