'initialized' event gets triggered multiple times

Always here: https://github.com/educoder/sail.js/blob/master/sail.js#L92

And also in the app after modules are loaded, for example: https://github.com/encorelab/CommonKnowledge/blob/master/smartboard/coffee/ck.smartboard.coffee#L34

That first initialized trigger (sail.js#L92) almost certainly needs to be removed. This gets triggered before the app is loaded, so is pretty much useless.
