CoffeeScript preferred styles

Use `@` instead of `this` for scoping

Prefer double quotes to preserve interpolation, allow for more complex strings,  make selectors easier to read and for overall consistency.
* `$("[data-role='title']")` or `$("input[type='text']")`
* `"Isn't this nice?"`
* `"It is #{nice}"`
@gabebw  the notion to use `@` instead of `this` may be more about context..not scoping. I was trying to state that we should use `@` when in reference to the object that 'owns' the currently executing code. This conversation came about when a client asked why we do:

```
constructor: ->
  @someMethod()
```
vs.
```
constructor: ->
  this.someMethod()
```
So perhaps:
`When referencing properties, use @ instead of this`
or
`Use @ instead of this, unless passing the instance itself.`
