Downgrade back to Node.js 0.8 now that node-apn supports it.
Make c2dm and gcm not crash on test message.
Currently they do not support messages that are not bound to an event.
Fix the DELETE /event/:event_id call.
Return success status from the redis event deletion and respond with the correct
HTTP response code.
Fix actual sending of broadcast events.
The eventpublisher never sent any broadcasts, because they were not found from
the redis database and therefore were reported as non-existant.
