Bug in case insensitive

[yairpe]

IMHO there's a bug that prevent this extension from working properly.

The code in MPTranslate.php saves the messages it finds without translations in lower case!

    function missingTranslation($event){
        Yii::import('translate.models.MessageSource');
        $attributes=array(
            //'category'=>strtolower($event->category),         // bug
            'category'=>$event->category,                       // fix
            //'message'=>strtolower($event->message),           // bug
            'message'=>$event->message,                         // fix
        );

The search is done in case insensitive way as intended
SELECT * FROMSourceMessage t WHERE LOWER(message)=:message AND LOWER(category)=:category

but if you save the message itself as lowercase, Yii itself cannot find it and get it's translation!

I believe that the same is true for the category but all my categories are in lower case so I did not check it.

Great extension. Thanks
