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}"`
I've used `@` for properties, but not for passing the instance itself. For example:

``` coffeescript
new Post user: @
```

I would use `this` instead of `@` there.
