Update whitespace recommendations

I keep coming back to this issue with code reviews, where my preference is to align similar expressions or values, but our goal is to avoid excess whitespace. That's understandable. However there are times when I find that lining them up increases readability - it could be just me, so I thought I'd get everyone's opinion on this, and if possible reflect it in the Code Guide. What I'd like to do is leave it up to the developer to decide if something can be aligned or not.

Example of what what we want to avoid:

```
x      = 1
y      = 1
fooBar = 3
```

Example of what I'm proposing as a developer preference/decision - notice that these are pretty close in length to begin with:

```
events: {
    "focus .search-input": "inputDidFocus"
    "blur .search-input" : "inputDidBlur"
    "keyup .search-input": "inputKeyPressed"
    "click .clear-icon"  : "clearButtonPressed"
}
```
