Title: Allow models to be set via the key attribute even if keySource is defined.

See #187 regarding this. Basically I just wrote a test case for the modifications that resulted from the discussion in the issue. Allows for a model to be set in the key attribute for a model even if you define keySource.

So with a model with a key of forum and keySource of forum_id with the following values

```
{
id: 1,
title: "Hello World",
forum: {id: 1, title: "Cupcakes}
}
```
and
```
{
id: 1,
title: "Hello World",
forum_id: 1
}
```

Would both work fine.
