Prevent multiple initialization

[phillipberndt]

Apparently, it's easy to get things wrong and call timeago() multiple times on the same element. It would be great if the init function would in this case not set a new interval without clearing the old one, e.g. if you'd replace

if ($s.refreshMillis > 0) {
    this._timeagoInterval = setInterval(refresh_el, $s.refreshMillis);
}

with

if ($s.refreshMillis > 0 && this._timeagoInterval == null) {
    this._timeagoInterval = setInterval(refresh_el, $s.refreshMillis);
}
