only setup bootstrap growl notifications once. i still don't get this.

this issue is caused after browser.resetDom(), which happens on (1)
cron, (2) reset, (3) reroll. after which for some people this commit
will cause notifications to disappear altogether, while for others
reverting this commit will cause notifications to double.
