Issue: cases in switch statements not indented
prettier is printing cases at the same indentation level as their parent switch statement. I indent cases inside a switch statement.

Now:

```js
switch (something) {
case "foo":
  // ...
  break;
case "bar":
  // ...
  break;
}
```

Ideally:

```js
switch (something) {
  case "foo":
    // ...
    break;
  case "bar":
    // ...
    break;
}
```
Pull request description: fixes #56: indent cases inside switch statements
Fixes #56.
