chore(npm): Update astrolabe, and its references.

This new version of astrolabe allows you:

1. To create custom exceptions using

```js
CustomException: {
    get: function () { return this.exception('Exception Name'); }
}
```

You would raise this later by calling `this.CustomException.thro('message')`.

Also,

```js
lblThing: {
    get: function () { return this.findElement(this.by.css('div.thing')); }
},

tblThings: {
    get: function () { return this.findElements(this.by.css('div.thing ul li')); }
}
```

becomes

```js
lblThing: {
    get: function () { return this.find.by.css('div.thing')); }
},

tblThings: {
    get: function () { return this.find.all.by.css('div.thing ul li')); }
}
```

This will only work on the top-level astrolabe `this`. Any resulting
page elements come from selenium, and will not support this api.
