Why defaults don't match the github doc?

For example current user api handler [link](https://github.com/KnpLabs/php-github-api/blob/master/lib/Github/Api/CurrentUser.php#L122) in `type` field has `owner` value as default but according github api we [link](https://developer.github.com/v3/repos/#list-your-repositories) have `all` as default.

P.S If necessary, I can fix it by PR.

Thanks for this awesome library.

Start in lib/Github/Api/CurrentUser.php at the referenced line and compare the type field's default with the linked GitHub API documentation. Confirm the intended default and verify that the current-user repository request uses the documented value; done means the implementation and its behavior match the documentation.
