array_merge parameter orders are wrong in inherited classes

[GoogleCodeExporter]

Your default usage is:

public function rules()
    {
        return array_merge(
        array(
        array('email,password', 'required', 'on'=>'insert'),
        ),
        parent::rules()
        );
    }

This is wrong, as parent::rules() is the 2nd param for array_merge, and will 
overwrite if you define anything on top.

You should change this to:

public function rules()
    {
        return array_merge(
        parent::rules(),
        array(
        array('email,password', 'required', 'on'=>'insert'),
        )
        );
    }

Also add one for the Labels too!
