Some minor tweaks to spacing

[JustinDrake]

1. Consider expanding "qSA" for the new-comer.

2. "It's considered optional" -> it is optional?

3. "title = myPhoto.get("title")" -> too many spaces

4. "Accessing Model.attributes directly is fine for reading or cloning data, but ideally shouldn't be used to for attribute manipulation." -> Jeremy recommends not touching at Model.attributes at all. For reading or cloning data, he suggests toJSON.

5. "in scenario where" -> a word is missing

6. There are minor spacing consistency problems in the fragments of code throughout. For example "_.template( $("#results-template").html());"

7. In the "What is 'el'?" section you don't emphasize that you can use a combination of the methods to define el

8. "render() is a function that should always be overridden" -> render() is optional

That's all for now. Let me know if this is useful.

@JustinDrake Very useful. Thanks so much for putting these together.

I'll focus on getting as many of the items on your list addressed for tomorrow's round of updates as possible. I don't believe there's anything here that I disagree with at all.

@JustinDrake

I've made some updates to cover 1, 2, 3, 4, 5, 7 and 8.

In terms of 6, I think you make a valid point about spacing. I was considering following the jQuery style guidelines for general spacing across most of the book (which would require a further update), however I'm not sure how well this balances with how most Backbone developers style their code.

For reference, here's the style guide: http://docs.jquery.com/JQuery_Core_Style_Guidelines

(updated the issue title to reflect changes, let me know if further work is required on any). Thanks!

Closing for now. A style guide for the book is being worked on and will be getting applied in mid Feb.
