- Change the log.Fatal to a log.Println to avoid crashing (suggested by
https://github.com/oliviertremblay)
- Fix the output of the keyword helper -- don't try to cast an int to
string, use Printf instead (also thanks to
https://github.com/oliviertremblay)
- Start pulling the calls to each helpers Send method out into a new
function called 'broadcast(message)' -- In the long run, I'd like to also
pass in the array of helpers to send the message to.  This is a first step
in that direction.
