I made this a method to prevent other users from reassigning the
previously exported DefaultClient, e.g. doing something like:
```go
reddit.DefaultClient = nil
```

Now, instead of returning an object containing a list of results + the
anchors, we return just the list. The anchors are available in the
response object. Much cleaner this way in my opinion
go-github and godo do it this way too. They include some meta
information in the returned response objects
