Moving listeners to events on the DOM, docs, renaming

[alexander-alvarez]

First jab at making things a bit more idiomatic and reactive.

• removed the instances of .on and .off from html elements, in favor of adding actions directly on those elements.

First stab at adding documentation, will add more as I comb through the code

This is looking great so far. What else do you need to do to get this ready?

[alexander-alvarez]

seems the scroll event isn't being triggered in the ember 1.13 branch or something
the only difference I can thing of is the jquery versions jquery#3.1.1 vs jquery#2.1.4

I can add back the listener for only the scroll event if we don't know how to remedy it?
