/**
* 500 (Server Error) Response
*
* Usage:
* return res.serverError();
* return res.serverError(err);
* return res.serverError(err, 'some/specific/error/view');
*
* NOTE:
* If something throws in a policy or controller, or an internal
* error is encountered, Sails will call `res.serverError()`
* automatically.
