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}"`
Elliot, I like `Prefer @ over this for referencing instance properties`. It doesn't say anything about using `@` or `this` when passing the instance, but makes it clear when we do care.

That guideline gets my vote.
