When loading the aloha editor in ```Connexions/atc/master```, the selector being passed in is apparently ```.note:not([data-type])```.

This is causing jQuery to throw an error with the selector, since it's getting appended as ```.aloha-oer-block..note:not([data-type])```, which is invalid due to the double ```.```.

There's nothing being called from the atc code in the stack trace after loading aloha: ```@$el.aloha(@alohaOptions)``` (```@alohaOptions``` is ```null```), and ```@$el``` is properly loaded into the DOM before initializing aloha.

This change (or simply removing the ```.```) fixes the problem from my perspective.
