Closing project

Hi @kbsali,

is it possible somehow change project's status? I'm trying to close project, but unfortunately it doesn't do anything when I call:

```php
$closing = $client->api('project')->update($projectid, array( 'status' => 5 ));
```

$closing is true after the call, but status doesn't change.

**Update:** With 1.5.11 it returns false

Any ideas?

Thanks,

Martin
