fix(sync.js): trim dead branches on set
feat($goQuery): Experimental intergration of Query

$goQuery is a service built on `key.query()`.  It accepts a key, room,
filter and options.  It returns a QueryModel. The Model has the standard
`$sync` method which keeps the models value current with that of the
query result set.

```js
	angular.module('ChatApp').controller('ChatCtrl', ['$scope', '$goQuery', function($scope, $query) {
	  var filter = { “sender”: { “$eq”: “GrandMasterLivingston” }};
	  var sort = { “$name”: “desc”};
	  var limit = 20;
	  var options = { sort: sort, limit: limit };

	  $scope.chat = $query('messages', filter, options);
	  $scope.chat.$sync();
	}]);
```

docs(conn, key, model): Adding stability index

The GoAngular API will steadily improve as it matures. Certain parts
still need to be refined.  We want to make it clear which state each
part of the API is in, so we'll be leveraging NodeJS's stability index.

More can be found on the
[stability index here](http://nodejs.org/api/documentation.html).
