ApiListener#RelayMessageOne() relays every given message to the first connected endpoint Zone#GetEndpoints() returns. Randomness in combination with bad luck can direct more traffic (from a particular network segment) to one master than the admin wants.
This change lets the Zone#endpoints order prefer one endpoint over the other.
What does this change?
* Remove use of spaces for formatting
These could be found by using `grep -r -l -P '^\t+ +[^*]'
* Removal of training whitespaces
* A few lines longer than 120 chars
