Title: Listen for new releases and restart when they appear

Listen for new releases by periodically polling the Heroku API. When a new
release appears, call into the previously unused `restarter` function which
SIGTERM's the child process group and gives it ten seconds to stop. A SIGKILL
is then sent if the process has still not exited.
